Yeah, I know... personal taste :)
These are mutually exclusive the way I see it, and I would argue that personal preference is the right one.
I tried learning Ableton but didn't find joy in it, I think it's because FL Studio has closer origins to the music tracker days whereas Ableton avoided that.
I would say they both offer different mental modes that are orthogonal to one another
Instead of creating a LFO as part of the chain of devices it's clearly a thing embedded to the device itself, including on VSTs (so any VST can have more complex modulation than they offer natively). You can multi-target the modulator to affect any parameter on any of the devices across the whole track, so a LFO modulating something on the 1st device in the chain can also apply the same modulation to a parameter on the 9th device so they can be "coupled" to that movement, this mapping is also attenuated per application so even though the movement is the same it can have different magnitudes when assigned.
It completely removes the need of LFO Tool for complex curves/ramps, etc., or the LFO as a device with the "map" button to assign to parameters, if I want 10 LFOs I can just have them all together as a side-pane of a device or the track itself. It makes much more sense that a modulator is attached to something instead of being its own thing on a long list of devices.
Another improvement: macros can live on a control panel for a device, whole track, or even the whole project, so you can create a macro knob at the project-level and map it to affect any parameter of any track, and just map the project-level macro knob to a MIDI controller to modulate whatever parameter in the whole project.
These are just a couple of intuitive features from the top of my head I use in almost every single project.

Quick edit: another feature I remembered after writing this comment that I find more intuitive is the creation of control pages for a device, it's accessible right below the "modulators" button and opens a side-pane to create up to 8 control knobs mapped directly to a device's/VST's parameter or even mapped to a "macro" modulator which itself can be mapped to many parameters of a device/VST, it's really intuitive to create pages of these controls and only use the controls themselves to change parameters, I barely open the VST window after experimenting a bit with which parameters I want to play with and mapping those to controls.
