Tier for tier competitiveness the Patriot is probably the best one there, though it's not as good as it was. (and by the looks of things the E75 TS or the M54 renegade might power creep it further as better mobile premium tier 8 heavies)
Everything else there is pretty average to bad.
The 215b is bad, its a bad Super Conqueror, which is a bad T95/FV4201.
M60 is decent but not meta, it's like an HE proof Leo 1 with better gun handling, not played 121b but looks better after its buffs, like some sort of hybrid between a Patton and T-54.
Mutz is just meh, there are way better tier 8 premium meds. Same with Guard.
The tier 5 TD is just a premium Wolverine that trades DPM and gun handling for mobility.
The Pz IV Hyrdo is not a Panzer V/IV, enough said.
EDIT: If you aren't after a fairly rare CW tank then I'd say none, none of those tanks are actually very good.
215b probably has the uniquest playstyle, but not a particularly fun one as its a giant, slow, rear turreted heavy tank that has wonky armour and gets set on fire all the time, whilst also basically has a helicopter landing pad for arty to land shells on, so if you are after a challenge........
