yea you heard me,there's nothing called dragon or toad or snake sage mode,there's only sage mode,kabuto said he's no longer a snake,he's now a dragon right,it's a metaphor to emphasize his huge progress,he never actually said it's DSM,plus lets see what kabuto's sage mode have and compare it to naruto's:
kabuto has oro's chakra:his is too weak to actually be able to use sage mode.
naruto absorbs natural enegy by himself,while kabuto fused juugo's cells to his body to do that task for him,then both can use that in their tech.
kabuto learned in ryochido how to mix his chakra with natural energy to have the senjutsu chakra while naruto learned that in mount myoboku.
if you look at it closely both so called "different" sage mode have the same process.
PS:kabuto called his SM perfect because he can collect natural energy while moving, he has near endless chakra supply,yet he's not a better sage than naruto,naruto was able to absorb natural enegy by himself giving him high sensory abilities while kabuto didn't(he didn't sense itachi neither sasuke until they got in his hideout),also giving him the ability to control natural energy outside his body to use frog kata.
