I have a TRG-22 and love it but never fired a PGW Coyote so I can't comment on how they compare.
One thing to consider, 3 PGW Coyote's in the exchange forum currently with one of them being in there for a couple months now and another one offering a "payment plan".
Last TRG-22 to go up for sale in the exchange forum sold in under a week, there are currently no TRG-22's in the exchange forum up for sale and there is often a WTB looking for a TRG-22. Something to consider.
However that being said, the PGW is the new cool gun on the block... everyone seems to want one, but few spend the money to get one. TRG's are common place by comparison.
