Are frost dragon's worth legiting? (with pak yak)

I'm closing in on pak yak and ability to actually kill frost dragons
I'm jw now that the new whip update is approaching and whips have
been going up in price, is it still better to kill frost dragons using pak yak?

if so how much better is it to kill them over abyssal demons, I know
the frost drags are always crowded with bots and cannons but any
legit player should be faster than them, on the other hand abyssal
demons isn't as crowded and whips could very well which 3m+.

thanks
