Help me pick a 4-5" midrange.............

[Regore]

Grs makes an excellent 4-1/2 replacement for the old pioneer h/d drivers. Keeps up with my 15" woofers fine.
I'm using it as a midrange but could also be used as a mid bass. 91db spl and very affordable.

... The Dayton 2 inch dome seems to be highly rated where the Morell is universally not.

Are you referring to the Dayton RS52 and the Morel MDM55? If so, I'd say that the consensus is that the RS52 is, at best, controversial and the MDM55 universally admired. I can't remember anyone speaking or writing negative things about the Morel. Also, the RS52 is reported to have quality problems of late.
