To me they appear to be chalk and cheese and the first is little more than a slightly adjustable £10 cheap probe which allows you to dial out spindle run out but only if placed 100% accurately into spindle every time where as the Haimer type is a quality precision tool.

I would go for the standard £10 probe or the quality precision tool and dismiss the first but thats just my opinion, I can see no great gains from the design just a lot of faffing for little gain.
