Yes I can see the fun aspect of owning either one to play around with.
From what I've often heard is that Ozone is a pretty much all up limiter, multi-band dynamics, stereo enhancer, aural exciter, eq and is for that likely a good value solution for putting some finish on a track, where as Alloy's functions cover more track based mixing duties.
If you are a Sonar user you already have a good range of stuff already in the box most of the stuff in the Sonitus suite is perfectly up to the task there with an instance of the eq already built into the console strip ready to roll.
I'd would humbly suggest some working with what you have until you at least know what you are lacking and why a particular alternative would be better in your case which you don't at the moment otherwise the question would not have arisen.
To directly answer your question though if it was me I'd plump for Ozone as finding individual alternatives for the suite of tools on offer I would likely have to spend more than Ozone costs. With Alloy there are many alternative means of getting the same functionality with out being tied to the cpu penalty of having an all in one suite and probably with the functionality I'd use out of that suite I'd likely end up spending less too.
Having said that I don't own either nor do I feel I'm missing out anywhere currently
Of course YMMV, and plenty of folk just like having lots of gear and there's nothing wrong with that.
