The Alexia to me would have the nod, IF!!! you have the amp to drive them?? As they are a pig of an amplifier load down to 0.9ohm EPDR in the bass.
The Sasha 1’s were just as bad, and the Sasha 2’s are said to be a little better, but I've seen no graphs on these so that can't be verified, only the 1’s.

If you still have the Proceed Amp5 as an amp, this has no chance to drive the Alexia or the Sasha1 properly, and a ? with the Sasha 2’s
