Strut assembly KYB or Bilstein

Mine lasted 5 years on my 02.

KYB I have not had any issues with in normal use.

I went with KYB rear struts for my 07 Touring earlier this year and the rear feels tighter and more stable over bumps.

I purchased my 98 with ~200k miles in 2017 and had my mechanic replace all struts with 5100s. I'm currently at ~275k miles and the 5100s appear to be in good shape so holding off on replacing those again.

Bilstein 5100 struts, they’re absolutely fantastic. Have them on my FJ.

I would get kyb struts and reuse the springs.

I used the KYB Excel-G struts to replace both fronts on my MR2 Spyder until I got my BC coilovers and they’re fine. Not necessarily any harsher of a ride and they’ve seemed to hold up pretty decent (keep in mind your mileage really may vary as I only did a few thousand miles with them!)

I put those on a 2011. They are slightly stiff but super easy to drop in both front and rear. Really great on the highway but a little harder than I would like on local streets with pot holes.

I no longer use any quick struts. The ride sucks and they just don't last.

My kyb quick struts on my sienna lasted about 7 months. One leaked, the other top bearing plate failed.
