The Deluxe Skid/Flap are really good toys, but I feel that HA Skids is a superior toy in almost every way. Unfortunately I don't have an HA Mudflap to confirm my suspicions about both of them. BBBB is great too. I like the Size and weight that HA BB carries, but BBBB is a very poseable, fun little Bumblebee to fiddle with.
I'd always thought HA Skids looked cool, but never wanted to spend so much to get him. Plus, then I'd feel some kind of obligation to get the rest of the HA's too, and aside from Jazz and maybe Barricade, none of them really appeal to me.
Animated Deluxe Prime Rodimus Minor Leader Ultra Magnus Leader Megatron Shockwave Starscream Prowl (samurai or not) Leader Bulkhead Swindle Soundwave Any and all Lockdowns Jetfire & Jetstorm Blurr Movie 1 Leader Brawl Movie 2 Leader Starscream Human Alliance Jazz (you can find him on heavy clearance everywhere. Get him if you see him) Mindwipe Leader or Voyager Battle Blades Prime (both nearly the same mold, just depends on how much you want to spend or how much money you have Human Alliance Bumblebee Battle Blade Bumblebee Skystalker Bludgeon Sidearm Sideswipe Those are my recommendations.
Out of my collection these are the top 5 you should get Best 3 Animated I own: Rodimus Shockwave Blitzwing Best 2 Movieverse I own: HA Bumblebee Shockwave I just noticed 2/5 of the list is Shockwave
