Yep.
Binned the Sensah bitsa groupset best part of 2 years ago, as soon as (and the OP won't like this!) a cheap 105 deal came up.
The Sensah (which I only used because it was a pandemic era project & 105 was either unavailable or eye-wateringly expensive) was OK, but as I might've mentioned, the mech springs were
incredibly stiff. While this made little difference to actual shifting, probably because of the shifter design, it murdered the life of cables & outers, so you'd get maybe 1000 miles before everything just became mushy & unadjustably inaccurate. That was probably exacerbated by the fact my frame necessitates full-length outers, meaning more to compress & go spongy.
So the Sensah's on my indoor trainer bike now, where such things don't matter so much - & I barely use the bloody thing anyway.
By contrast the 105 (mechanical 11sp) has been excellent, flawless shifting & needing no ongoing adjustment once set up. I've only just had to replace the rear cable in the last month as it started to fray inside the shifter - like various other Shimano groups I've used, it became laggy & miss downshifts when the cable started to die. Replaced that & it's back to normal so presumably plenty of life left in the outer.
On the broader topic, I've used a lot of Shimano stuff, going back to the 'gold arrow' 105 back in the 80s & broadly it's been good to great - functional, reliable & often looking pretty trick too. Every bike I've had in the last 15 or so years has been Shimano-equipped & that's covered all the road range from mechanical Ultegra down to the 2300 that came before Claris - all a piece of p!ss to work on, set it up properly & it does what it's supposed to.
However I'm less than impressed with the direction they're taking with their range, and it's disappointing to hear this do-it-all Cues series is a drop in quality & functionality. Elevating 105 to borderline unaffordability & binning the lower tiers rather than upgrading the tech seems like a mistake, and I suspect they may lose that affordable midrange market to the likes of Sensah & LTwoo if those brands continue to improve their tech. And that ain't a bad thing.
