im an audio engineering student and use both extensively for my school stuff
IMO logic has more and better instruments but ableton has a much much better workflow
here’s some of my comments regarding the two, some are + , some are -
in logic, I really dont like how the ultrabeat shaves off the first few ms of audio, you can hear it if you load a really punchy kick with a lot of transients up front and then loading it to ultrabeat and making it sound “weak”
in logic i love how the ES2 can pretty much do anything - if you get to know it inside out, its pretty damn powerful
in ableton, i love how you can group tracks together and they become like a BUS, its really really easy, and fast, no fuss, oh and sidechaining stuff takes like ONE CLICK literally
in ableton i love how simple and easy to use OPERATOR is - good for carving out bass, sub bass, or anything really
in ableton the clip launching sometimes works in your favour in creativity, for example rather than laying down stuff on the sequencer you assign stuff to the clips and launch them as if you were playing traktor, you can often get really really awesome creative ideas this way, if the idea is set you can just press record to record these into the sequencer
theres so much more that i can say about the two, you really wont lose much by choosing just one, in the end they all do the same thing with slightly different workflow
just pick one, master it, and you will be fine
if the $200 logic that they sell now includes all the instruments fully then i think its a really good deal to get into logic, all the included instruments are awesome and saves you from purchasing extra instruments for awhile
