Tanks just wouldn't be fair. Seriously, I'd have to rate tanks higher than Mechs by a wide margin, as in Heavy tanks would be a match for an Assault Mech. God help you if you stumble across an Assault tank, because you'd just get stomped.
The only things that would compete would be Lights and some Mediums, by virtue of being fast.
Look at the 90t
Challenger for example:
1x Gauss Rifle (2 tons, turret)
1x LB-10X (2 tons, turret)
1x LRM-10 (2 tons, turret)
2x SSRM-2 (hull, side)
2x MPL (hull, front)
1x SPL (hull, rear)
14 tons Ferro armor
270 XL
54kph
Or the 100t
Behemoth:
2x AC/10 (turret)
4x LRM-5 (fixed hull, front)
2x SRM-6 (turret)
2x SRM-4 (casemate turret, hull, front)
2x SRM-4 (turret mounted ball turrets, 1 each)
4x MG (2 in each ball turret)
Unknown armor tonnage
GM R200 ICE
32kph
EDIT:
Oh, and then there's
this monstrosity:
1x AC/20 (turret, "generous" ammunition stores)
1x AC/10 (turret, "generous" ammunition stores)
1x AC/2 (turret, "generous" ammunition stores)
1x MG (hull, front)
40.5 tons Ferro armor
350 Fuel Cell
33kph
