01 — Start here
They are the same program at different settings
Apple builds both, and Logic Pro shares GarageBand's audio engine, its instruments and much of its interface logic. GarageBand is not a different, lesser product so much as Logic Pro with most of the controls hidden and the harder decisions made for you.
That has a practical consequence worth knowing before anything else: Logic Pro opens GarageBand projects directly. Your tracks, regions and instrument choices come across. Nothing you have made so far is stranded, and you can move when you are ready rather than starting again.
It does not go the other way. A project saved in Logic Pro will not open in GarageBand. Once you move, you have moved.
Keep a copy of any GarageBand project you are fond of before opening it in Logic Pro. The upgrade is one-way and the original file is overwritten if you save.
02 — What you get
What Logic Pro adds that GarageBand withholds
Track count is the first wall people hit. GarageBand caps how many tracks a project can hold, and Logic Pro effectively does not. For a full arrangement with layered instruments, this alone is the reason people move.
The mixer is the second. Logic Pro gives you a real mixing desk with busses, sends, groups and full plugin routing. GarageBand gives you a volume slider and a small set of preset effects. If you have ever wanted to send three tracks to one reverb, that is the difference.
Then there is depth: a far larger instrument and loop library, proper MIDI editing, Flex Time and Flex Pitch for correcting timing and tuning, Smart Tempo, scoring, surround, and the kind of automation you need to shape a mix over time rather than set it once.
Logic Pro is a one-off purchase rather than a subscription, and Apple has historically offered a free trial long enough to judge it properly. It is also available on iPad on a subscription, which is a different product decision with the same name.
03 — The honest counter-case
When GarageBand is already enough
GarageBand is free, it is already on the machine, and for a very large number of people it is not the limiting factor. If you have never hit the track ceiling, never wanted a bus, and never been stopped by a missing feature, the upgrade buys you options rather than results.
The clearest signal to upgrade is a specific frustration you can name. If you can say what GarageBand will not let you do, Logic Pro probably does it. If the reason is that Logic Pro is what serious people use, that is not a reason and the extra interface will slow you down.
Take the trial, open a real project in it, and see whether you reach for anything new. A week of honest use answers this better than any feature comparison, this one included.
A useful test: list the last three things you wanted to do and could not. If none of them are on the Logic Pro feature list, the money is better spent on a microphone.
04 — If it is a podcast or a voiceover
Neither one is really built for this
This is the part most comparisons skip. A large share of people weighing GarageBand against Logic Pro are not making music at all. They are recording one or two people talking, and they are choosing between two music programs because those are the two they have heard of.
For spoken audio, Logic Pro's advantages are almost entirely irrelevant. You do not need unlimited tracks for two voices. You do not need Flex Pitch for a conversation. What you need is clean recording, removal of background noise and filler words, consistent loudness, and a way to publish. Neither program does the middle three without real manual work.
Editing speech in a waveform is also just slow. Finding every um in forty minutes by eye is an evening's work, and it is the main reason people abandon podcasts after four episodes.
Hilite exists for this case and we make it, so weigh that accordingly. It edits speech as text, removes filler and noise, levels the result and publishes it. If you are making music, ignore this entirely and go back to the comparison above, where Logic Pro is the right answer for the right person.

05 — The short version
Who should buy it
Buy Logic Pro if you are making music, you have hit a limit you can name, and you intend to keep going. The project upgrade path is clean, the price is one-off, and it is a serious tool at a price well below what professional studios used to pay.
Stay on GarageBand if you are still learning, working on small arrangements, or unsure. It costs nothing and it is not holding you back yet.
Use neither if the job is a voice. Both are music software, and a podcast is not a music project with fewer instruments. It is a different job that wants different tools.
If it is a voice, there is a simpler answer.
