After some miles on my 214s with Toyo non-RFTs (coming from Michelin 19 RFTs), the ride is noticeably softer. Going over bumps (normal and sport mode) feels like a normal car again rather than a big THUMP I both heard and felt. I can't say for sure it's more agile but the wider footprint does make it a slightly heavier at street-corner turns - slightly. Road noise to me is non-existant right now, just like it was with the RFTs. All in all going away from RFTs is well worth the softer ride in my opinion.
