I had the electric blue and never really loved it, I think due to the bezel. Another factor was the "bond" bracelet that was on my EB - I would have liked it better with the "speedy" bracelet. Being a man with similar sized wrists (6 inches) I personally think the 42 is pushing it but still works. I love how Omega's bracelets have enough links to take out to fit wrists like ours and have the clasp centered. For my 5 digit submariner I needed to have a permanent link removed..
Anyhow, I ended up selling it (the EB) when I got a 2254.50. I liked (and still like) the black one much much better than the blue. If it were me, I would sell both and get a 2254.50 and an Omega mesh to swap on and off and call it a day. Alternatively, you could go the modding route and pick up a blue bezel and slap it on, I think that looks good as well, although not technically kosher.
The midsize looks too small to me, and I am a guy who generally prefers smaller watches. Some pics:
