Some informations if you’re into other things than Shuttle Control (Cargo4) just to let you know how things have change since 1 year from now 
- Shuttle Control Configuration with OT Preset Endorphin.es tutorial
- Cargo4 Screen with all its presets
- Cargo4 OT Preset
My POV :
PROS
- my knowledge of OT
- Benefit of all sampling capabilities of OT
- Benefit of MIDI in Modular with the powerful sequencer of OT etc.
- Benefit of Modular with now a lot of space, because of externalization of sampling module, and sequencer module (some may need another one in the rack…) etc.
CONS
- I just begin my journey with this setup, so none for now
