I'm a bit of a minimalist and tend to not like collectible stuff.
But if I were into Legos then I'd say the alternatives to the name giving brand that is the Lego company, you know stuff like BlueBrix, are waaay nicer.
I was a fan of legos, but after gave up on all of it's IPs for making established IPs lego set. I stop caring too much, but have been tempted to get some old classic sets once or twice on Ebay and all.
