It depends- if it were an early Bushka that was simply a titilist conversion; I would be more leaning to a Szamboti. However, it it were a later GB, with perhaps a Spain forearm and some nice pearl inlays and other work by George, then I would lean into the GB a bit more.
There are a lot of Palmer cues that sport a Szamboti front end, and some nice third catalog Palmers, like the model 12, actually look like they came from Gus himself, and they play like a Gus as well- it is a very economical way to appreciate Gus's work and spend perhaps $600 to $1200 as opposed to forking over $6000+
Either way, if you are into lighter cues for playability- say 18.5 ounces - you won't find that in many of either Gus' or GB original cues- many of them were 20 ounces and heavier, with shafts somewhere between 13 and 13,5 being common.
I sold my Gus Palmer simply because it was just too heavy to play and I don't like closet queens - but it was a great example of Gus' point work and the density of his BEM choice wood for the forearm - hard to find wood like that anymore for cues or baseball bats
