The Celestron has a carbon tube, less weight and less focus drift, but the stupid mirror flop. Meade LX, better optics and no mirror flop with the focus lock. If your mount can handle the extra weight, and you refocus now and then, Meade is the go ("RC" optics, and isnt an equivalent Celestron more expensive?). BTW, I dont bother with regular refocusing and I image without meridian flip (without an ME, you have to be joking). As Roland states, coma on the ACF is better, the rest is carefull attention (eg collimation, not that ive checked mine recently)
Megadata my friend, thats the key, regardless of OTA.
