Nice link. :) And as the author of the above linked blog, please let me comment: I'd definitely go with a SP Gigapower over a PocketRocket.
The MicroRocket and the GigaPower are a bit more closely matched, but the GigaPower is $40 whereas the MicroRocket is $60. I think you would do well with either the MicroRocket or the GigaPower, but I would definitely not pick the PocketRocket. Despite the PocketRocket's popularity (why?!), I really don't think it's the best stove. There are certainly a lot of others out there of that general type (SnowPeak LiteMax, Kovea SupaLite, MSR MicroRocket, SnowPeak GigaPower, etc.) that I would pick before considering the PocketRocket.
I like the Vargo JetTi (bought one for my little sister), but I think in retrospect that I prefer some of the others listed just above. The JetTi's pot supports are just a tad short in my opinion. Besides that, I think the JetTi may now be out of production.
The MSR Titan Kettle is a good product, and I've gotten a lot of good use out of mine although I typically use it with a Caldera Cone from Trail Designs which is an alcohol set up.
