I prefer the flavor of the three I named over the flavor of the SRP. Just my personal preference. To me, the SRP had a pleasant sweetness with a hint of floral in some of the pods (it reminded me a little of rosewater), but the floral aspect disappeared pretty quickly. Heat levels on the pods I grew seemed to vary wildly from almost none at all to pretty darn spicy, but that was a few years ago. Perhaps the heat levels have stabilized more since then, I don't know.
Brazilian Starfish has an interesting pod shape and is a big productive plant. The pods are very sweet and sometimes I also detect a berry-like flavor. Yes, occasionally there is also an initial floral/soapy undertone. But the floral (when it is present at all) usually dissipates quickly, leaving just the good flavors. Heat on these is around Serrano level. It is one of my favorite peppers for eating fresh off the plant.
Aji Fantasy Orange is one I grew for the first time last season. It had a nice citrusy undertone that I liked. It was less sweet than the Starfish, and had only a very slight soapy/floral that went away quickly. These were even less floral than the Starfish peppers. They seemed to be around Cayenne level heat to me.
The Aji Rainforest peppers that I grew had a sweet flavor similar to Brazilian Starfish but with more rounded to pear-shaped pods growing on relatively more compact plants (Starfish plants can get pretty tall and big). There was also a floral undertone with these, but it was fairly subdued and was more flowery than perfumy in character, if that makes sense. These also seemed a bit warmer than the Starfish to me. The ones I grew seemed to be a little below Cayenne heat level.
