Im in the industry (ex OEM dev guy) tuned many a prod vehicle over the years (mostly european)
My $0.02 worth ......
Personally Id go Bilstein everytime .. done plenty of work with Billy guys ... great product and they know their stuff
I have Bilsteins on my 993 Porsche (stock Monroes done at 20k) (I track it, so its worth the cash to do)
The wifeys Mazda 5, Monroes (rear ) failed at 11k .. (KYB's still running after 65k further )
Had plent of other experiences also ..
In short .. every experience with Teneco branded equip has been very poor .. both performance spec and longevity ..
Cheap is for a certain market ...
Nuff said .. Its my pers opinion - hope I dont offend ..
