I totally agree. I have a detolf filled with Hot Toys and one mostly filled with SS Star Wars figures. I really enjoy my sideshow stuff and I think it looks beautiful.
It's hard to relate the two really....but I would say that the Hot Toys win in quality and materials. From my collection my Hot Toys are simply more ambitious projects (DX13, DX09, DX08). All the same, my sideshow figures look great and were slightly better priced. I do not have a face sculpt character (not counting Vader deluxe), but I am taking a plunge into Hot Luke.
Sideshow will still make Star Wars figures and the reason why is because of how big the fan base is. I think Hot Tiys will make the iconic characters, the ones that defined the Star Wars universe...Han, Chewie, Luke, Stormtroopers, Vader, Fett, Leia, Ben Kenobi, Anakin... Basically characters that appeal to more than just diehard SW fans. Sideshow, on the other hand will make the less iconic characters still. Like the tie fighter pilot, jango Fett, at at driver, imperial guard, clone trooper variations, greedo, scout trooper, ect. Sideshow will even do various, less iconic variations of the main character...Hoth Luke, Hoth han, pilot luke, proto Fett, ect. So it comes down to what you want sometimes. That what it is for me....I mean I wanted one Luke in my collection and I wanted an ESB version so got the Hoth Luke. May not be the best ever....but I like my SS figures so I know I'll be satisfied.
When I go through my collection, some of my SW figurs I absolutely love and they catch my eye as much if not more than my HTs. Like my Snowtrooper, Vader, Boba Fett, clone trooper vet....these are all amazing in their own right
So don't be so fast to completely eschew the SS stuff.
