In my opinion, the exact opposite is true: the above variant has more flame than the original #4, because there is no distracting circle, the stem of the d is more flame-like, and the flame itself (the top of the P) extends to the same height as the stem of the d, which makes it more prominent than the original #4.The flame is nearly, if not lost, in this version.There needs to be another poll without the word Pyra under the logos.
This variant of #4:
with #2's Pyra font.
The original #4 does indeed spell "dp" in lowercase. The variant above spells "dP" though. I don't know if that is better or worse according to your case-sensitive aestheticsGiven that my vote was based more on which I disliked least as opposed to which I liked most, I've been trying to understand why I dislike #4 so much. I think a big part of it is that the lettering (in the logo itself) is in lower case which gives it a 'wrong' feeling. I can't help feeling that the lower case lettering detracts more than benefits gained from being an ambigram. Of course that's entirely a matter of personal preference on my part, but it does leave #2 as the most aesthetically pleasing to my eye.
