A direct-drive smart trainer against smart rollers: setup, ride feel and where each fits.
Verdict
Buy the Wahoo KICKR CORE 2 if you want a stable, direct-drive trainer with Zwift Cog, Zwift Click shifting, WiFi and strong hard-effort and structured-training performance. Buy the KICKR ROLLR if you want a free-moving, balance-based ride with no wheel removal or cassette and you can accept the higher price.

Rollers require balance and some practice, especially at low speed. A direct-drive trainer holds the bike upright, so it is easier for hard intervals.
On the KICKR CORE 2, yes. On the ROLLR, no wheel removal or cassette is needed.
Both work with Zwift. The CORE 2 includes Zwift Cog and Zwift Click support listed here.
