You can’t build the clawbot with the competition super kit, but if you buy the claw kit separately (link) and do a bit of cutting, you can end up with something very similar.
But for competition use, I think you’re probably better off with the hero bot as a first build anyway – and you can build that from the super kit, although some cutting is required:
Or at least, you can this year (and IIRC you could last year too) – no guarantee that next year’s hero bot will be buildable with the super kit, but looking at the selection of parts in both kits I would say it’s likely.
Given that all the parts in the super kit are useful, and that it offers the most savings compared to buying all the parts individually, the super kit is definitely what I’d go for if it’s in the budget. If not, the starter kit is a great option.
