ML Aerius or SL3's?

For the same price - which of the two ML's are superior. I'm in a situation which has presented itself where 2 ML pairs are available - 1 pr of Aerius and a pair of SL3's.

I'm currently running tube gear as amplification but I may stray over to the transistor side for these puppies.

Please advise - I'm not really interested in any others in the ML line as these are the only 2 that are available to me at this time.

Again, they are asking same price and I feel that I need folks in the know re: ESL's and these 2 in particular.

Thank you in advance!
