Ventus 2CT or 2CM or DG 808b or ASH26E or LS8t

I intend to buy a state of the art new glider and I was looking at this
choice.

My main priority is to enjoy the flying and so I want good performance, nice
handling and safe behaviour (no incipient spin tendency to keep me on edge).
I am not sure if I will loose a lot of climb performance if I go for a self
launcher as they are clearly heavier than a turbo, is the convenience worth
loosing the advantage of the low min weight? I Am flying in the UK mainly
and so small feeble thermals are the rule.

Can those who have flown these aircraft please let me have their comments
and help with my decision.

Thanks.
