SRAM front derailleurs are fine when you avoid the competitive cyclist shill install method. That being said, my recent experience with ultegra has been pleasant. However seeing that Force is essentially a heavier red, id say Force is nothing to look over as well.

how to install you ask?
cable detached:
1. Align height, 1-2 mm from top of teeth of big chainring
2. Finger tighten screw
3. Manually pull out derailleur
4. Align 2 lines on front and back of cage parallel to that big chainring
5. Fully tighten screw at that rotational adjustment
note: you’ll find that tightening rotates the derailleur a smidge outboard, compensate accordingly.


shimano shifters are a little more ergonomic
sram is a lot lighter which makes a difference on the front
sram takes just a bit more effort to shift but the feel is also there for sram
And of course with sram you get one lever for both up and down shifts instead of two which for me is simpler and faster
