Trainer Poll: Kickr v.5 vs. Kickr v.6

[exapkib]

Trainer season is on its way!

Because of . . . circumstances . . . I face the following choice in purchasing a used trainer:

--Low-mileage Wahoo KICKR v.6 for $200
--Low-mileage Wahoo KICKR v.5 for $50

The last trainer I used was a Kurt Kinetic, which was great for what it was. After moving away from Michigan winters, I swore off riding inside, but life changes have brought me to the point at which I would like to have an indoor option through the coming winter.

I've read through the usual spots online (so grateful to DCRainmaker for his contributions), and can't tell if I care enough about the upgrades to pay the extra money for the v.6 trainer.

What say you? V.5 or v.6? Something else?

Thanks in advance!
