*By no means an expert opinion*
Doesn't look too special, and... kinda costly to deploy? Only thing going for it is that 5% base crit chance, 15% penetration and a fairly high base damage output.
The M24 Chaffee on the other hand looks a beaut. A little short ranged, but high evasion, solid rate of fire with a complimentary passive skill and a peerless active skill. Sure she's fragile and the portrait's slightly wonky but she looks well worth having.
