While Gringo's Zouaves are indeed nice the Perry's are easy to convert...you just need a sharp blade! 
The less you have to convert (i.e., cut off details) the better IMO.
YMMV.
Eye of the Beholder thing I assume.
Great as Perrys' miniatures are there are others that would work better in a person' evaluation since they are mortals, no?
Not a fan of 25 plus mm figures any more (other than skirmish) so my opinion is worth what you paid.
Gracias,
