I think XM's homeruns are Luke and Darth Maul.... The Vader set is meh at best.... As for Bobba Fett I personally liked it better then SS version but I do prefer Sculpted over Mix Media.... I think Iron Studios nailed Darth Vader and Yoda but was so so with their Kylo Ren...
SS is lots of hits and misses... Some of their Vaders and Fetts are not bad and they did ok with Rey and Jyn but they have a lot of stinkers like chicken legs Sandtrooper and their new Stormtrooper that looks like his armor shrunk in the dryer, then their new Luke PF is horrible IMO, bad pose and a bad portrait... Their new Solo PF pose is not bad but the portrait looks cartoonish...
I saw MYC Sculptures new Ahsoka Statue today and I was pretty disappointed by it, the portrait doesn't really look like Ahsoka and she has a really weird chest plate... I really wanted an Ahsoka in my collection but unfortunately this won't be it
All you can really do is cherry pick from all the companies that make 1/4 Star Wars stuff...
