Not all omnis are created equal, but "better" and "worse" is always going to be in the ear of the beholder.
Omnidirectional response can be achieved in several different ways, each of which has its own particular "flavor", heard varyingly as pluses and/or minuses by each listener. The multi-material, full-range Walsh design (one variety of which is still being manufactured by Dick Harter) has limited max output. The MBL can safely deliver crushing SPLs. Score one for MBL (if you listen loud). However, the bass response of the MBL isn't as tight and defined as the Walsh. Score this one the other way (unless you prefer the bass "bloom" of the MBL). This stuff is always a matter of trade-offs plus personal sate.
The Ohms aren't omnis above 7khz, IIRC, so that's a cheat - if you care about "design purity".. Bose gets very wide treble dispersion in some models by angling tweeters back against the wall. The Duevel, Robertson (sic?) and Mirage models use a similar idea (fire the tweeter upwards against a deflector) to get 360 degree treble. Gallo uses a tweeter with native 180 degree dispersion in the treble, but that only kicks in above 2khz, where dispersion at the top of the mid/woofer's pass and has already narrowed.
Which design is overall "best" and why? I don't know, but I'm pretty sure that if you played em all for ten different 'Goners, you'd get ten different answers.
