I guess this explains the reason why Burta is faster than the other Ginyus (except Captain Ginyu who was obviously faster than Burta since he was able to tag Goku and keep up with his speed).
Personally I'd find it more interesting if things didn't line up exactly.
I.e. it'd be neat if there were characters who were, say, pl 40,000, but as strong as a 20k while fast as a 60k.
And Burtur's line about being fastest in the universe kinda fits that, but of course, aside from USSJ and bulky Cell, that never happens.
Dragonball Multiverse did a cool thing where they had Trunks switch back and forth between USSJ and ASSJ depending on whether he needed speed or raw power, all in mid fight.
In a way, they kind of did that with Burter. In the manga, Krillin stated that Jeice/Burter had the same ki-level as Recoome: http://i.imgur.com/YrN48eR.jpg
...But at most there was only a very slight difference between their respective power levels. Despite this, Burter was still faster than any member of the Ginyu Force(sans Captain Ginyu himself) by a wide margin.
He was also the largest/bulkiest member of the Ginyu Force: (please log in to view the image)
...Which obviously didn't hinder his speed at all.
But mutants also tend to be pretty f*cking illogical, even by DBZ standards. Hence Freeza(a mutant) reaching SSJG+-level power with only 4 months of training, lol. /shrug
That's the thing, they talked about how fast he was, but it didn't show much. I don't really recall much sign that he's all that faster than Jeice, he just talked about speed more.
Aside from that, his only other showings were against Goku(who was obviously FAR beyond him.)
But even Captain Ginyu wanked Burter's speed: (please log in to view the image)
Even though we know the Captain himself was faster, it's clear that Burter's specialty was speed. If Jeice/Recoome would have been equal in that area, such an emphasis wouldn't have been placed solely on Burter.
I think they were talking about Burta flight speed rather than his combat speed. I guess Burta and Jeice didn't do that move where they spun around in a circle at super speed turning their body into energy in the manga. Dang!!!
