I kind of agree with you.
I have 3 Levos , One with T-type, one with Axs, and one I built up as a spare for when have guests, and that one I put on Shimano XT link glide.
I enjoy the AXS as it shifts the fastest, but the best shifting group is the XT link glide..... UP AND DOWN.
the T-type is sure footed but slow.
Next time round with the gen 4, I think I'll get the frame option and put on XT link glide. Let's hope they keep the cable ports unlike what they have done with the new stumpy.
It's the same as buying a new iPhone every year.... you think it will make a huge difference in your life but after a few weeks you realise its the same, that's how I feel about T-type
On that note and to keep it on topic.
Gen4:
New 110 motor.
BLuetooth remote. (Wireless)
New TCU screen
No sidearm
Higher capacity battery.
