Opinion needed: 2001 S60 T5 VS 2005 S80 T6 driver seat comfort

[CIK7]

I ONLY want opinions from people that have had at least a good amount of time with these SPECIFIC trim models to tell me how they like the comfort of the driver seat.
2001 S60- T5 trim only, not base trim
2005 S80- T6 trim only, not base trim
I use to own the 01 V70 base trim model, which those seats come in the V70 2.4T and XC, as well as the 01 S60 base/2.4t. I assume the T5 has more comfortable seats because it is an upgraded trim.
I specifically want to know if the 05 S80 T6 seats are more comfortable than the S60 t5.
I traded my 01 V70 base (17x,xxx miles) for an awesome 98 V70 XC (143,995 miles). I've had it since 9/30/19 and have finally decided I'm going to salvage the upholstery from another newer Volvo ($7.50 for whole seat, NOT a typo) to replace my XC (driver) upholstery. I have an extra driver seat from my junk car to use as guinea pig.
