"close" to the performance of the G2. That is, if you hunt in the 'd1' or 'd2' Tone ID function it will be better than using the 3 or 4 tone audio ID.

I have a G2 that does wonders in iron. I am a coin shooter 90% of the time, and was wondering if the Omega might be a better fit for me.
I wanted to work with the 5" DD coil exclusively last fall so the end of August, on the 30th and 31st, I mounted up the 5" on the Omega and used it at a few building tear-down sites near my place. I liked what it did in the iron junk.
Then I decided to leave it on the Omega for the entire month of September and use it for all of my coin hunting. I am mainly a "coin hunter" of the more varied type in that I like to hunt for coins, but that includes all smaller-size target such as trade tokens and silver and gold jewelry. Most of the time I look for renovation work, vacant lots where old buildings once stood, and similar places.
I hunt the fringes and overgrown parts of older parks, recreation sites, etc., etc. In town I'll hit the playgrounds for 'flash money' as well as good jewelry since I average 12 gold rings a year from the wood-chip and sand-filled playgrounds, alone.
Now, last year I took a fall off a ladder at work and was on-the-mend through July and August and was just starting to deal with the pain from four broken ribs, a severe concussion, a ruptured right eardrum and I hobble around anyway with my cane. Still, in September alone, I manged 895 coin hunting mainly some schools and parks (mostly 'lawn hunting') when I got away on a trip with some friends, or just trying to get back into moving as September began. Omega w/5" DD = 895 coins isn't bad, plus the 14 k diamond ring and over a dozen sterling silver items didn't hurt, either.
Today I could do better as the ribs have healed and in general I'm closer to what my normal would be.

I like the Omega w/stock 10" Concentric coil, but the 5" DD coil staid on my spare lower rod because it was a great switch when I hit iron littered sites ... which I do, often.
When I started working on my field evaluation of the then new Teknetics G2, I picked mainly the junky sites I have within a short drive and I tried all coils on the G2. The stock 11" DD is 'OK' for more open sites or for the beach, but I really liked the 5" coils performance on the Omega and found it to be the better coil, for me, on the G2. I left it mounted on the G2 ever since then.
Now, back to your question because you already have a G2. if you can handle the G2 w/11" DD coil, and if you have the 5" DD already, then I would suggest you get the Omega and use it with the stock coil and the 5" DD coil;. keep the 5" on a spare lower rod and you can swap it onto either of those detectors in a hurry when needed.
I like the G2 for certain tasks, such as hitting high-trash sites. However, I also like the Omega w/5" for the same applications, and the Omega gives me better overall depth of detection than the G2, and the target ID and VDI and Coin Depth read-outs are all more useful (for me) using the Omega. I would say that, even though the two models are different in their processing a little bit, I feel the 5" coil performance on the Omega would be about as good, and possibly better, with the Omega since you are more inclined to coin hunt.
