No. Not when you are talking the boge. There are many times I put the 808s up on a pedestal but boge 510s and 808s are pretty much the same. The 808 threading allows for more juice but on a standard carto, it makes little difference. On a bigger cart with ego threads, obviously you lose a lot of space to accommodate for the ego skirt threading. I've had less 808s be bad from boge but they aren't as popular so they aren't churning them out as fast.
Now the echos, there is a world of difference between the 808 and 510 version, so I can't say that as long as it's made by the same manufacturer it will be the same. But with the Boge's, they are pretty similar.
