This is a bad Porcupine Tree copy?

[Pelata]

Katatonia simply owns them when it comes to the level of pure emotion in their music.

Translated:

"I like Katatonia better than Porcupine Tree."

Just because one person can "feel" Katatonia and cannot "feel" Porcupine Tree does not mean Katatonia "owns" Porcupine Tree...I'm sure there are plenty of PT fans who gain no emotional connection when they hear Katatonia...

is more appealing to me

This is a much more rational statement, IMO...sums it up.
