What types of projects are you working on?
Are they heavy on the MIDI side? If so, are you making extensive use of outboard/hardware synths?
Do you need notation?
Are you primarily tracking audio?
With more details... we can make better recommendations.
Studio One has the cleanest UI... and has a nice balance of audio/MIDI features.
Has a gap-less audio engine, lots of included content, no notation
Cubase has extensive (more esoteric) MIDI editing, notation, etc.
As such... Cubase is popular with composers.
ProTools 2018 has just about caught up with the best native DAWs (feature wise).
If you haven't used ProTools, it'll take some time to get configured (setting up the I/O, etc).
You really can't make a bad decision with any of those three.
Spend some time with all three.
One will likely "jump out" as a better fit for your scenario.

Ableton Live is a great DAW application, but it's focus is more on the creative/performance side (much different from a standard "linear" type DAW). IMO, Live is best paired with another more traditional type DAW.
