Rick,
I've owned both and I sold both. I also apologize in advance for the lengthy post below. I do hope it helps you think it through.
In answer to your question (IMHO) the Eminence was closer to my acoustic upright than the Allegro. Both sounded great with my preference of DB strings, and again (IMHO) the Eminence sounded better both arco and pizz. Depth of arco was good with the Allegro, pizz "okay" (sounded like "many" amplified uprights) but needed just a touch of reverb to get some "air" into the tone and sound better. Eminence didn't need reverb to sound great on both.
Whether you will be satisfied with either really depends on what your goals are. I used both in my days subbing in Jazz trios/quartets and in a church band. My particular goals were oriented towards having a suitable substitute for my upright in snowy Colorado winters. Both fulfilled nicely.
Initially I sought an EUB with "most" of the physical references of my upright. As my skill progressed, the physical references became somewhat irrelevant.
Ultimately after I sold both, (and went through a Yamaha Silent Bass too) I then bought a NSD CR4M, a neck heel and an end pin stand. For my needs arco and pizz were great in a much smaller package. I even took my NSD to Japan and Hawaii. It travelled well and played great, and was in a much smaller package. Note that I've also bought and sold several NSD CR's over the years - and recently rebought one. Every time I've gone with the same setup as above.
So, while my specifics may differ from the outcomes you seek, I truly believe that you must define what you want out of an EUB before buying any specific one.
Determine whether it's tone, physical references, portability, or something else - then it's the music you play/want to play, and whether your bass will be acceptable to both other musicians and the audience. Perhaps (best case) both the musician's and the audience's egos will be checked at the door and your first notes will slam them to the floor.
Oh, and on another topic, think clearly about how you will be amplifying your EUB. Since I do double on both upright and BG and where I'm playing (generally) focuses on one or the other, I tend not to bring both to a gig - I'm either on BG or upright/EUB. BG gigs have one type of rig and upright/EUB requires another. On upright/EUB I run a very SMALL rig. With a small rig for both acoustic and EUB, I've found that it becomes much less distracting to the audience and my fellow band mates, especially if they are running acoustic only.
Again, this is all IMHO. YMMV...
