Don't have a specific tier list but from what I've watched anything that has lvl 3 soft and lets you put in side plates is pretty much S tier. pic rel is probably the best, but shit like cpc, gzhel, thor, bagariy, zhuk (emr), ana m2, korund is nearly as good. Be aware that zabralo/redut are too heavy and movement debuff is too severe to make them top tier.
If you want something affordable you can get defender from sledgehammer barter, although you can't put side plates in it
