Rt/E and Rt/N

Im deciding between a Rt/E and Rt/N build. What are the advantages/dissadvantages of both. Personal experience would be appreciated.

what do you plan on doing as a rit?
for summoning lots of spirits, iv seen the elite Glyph Of Renewal to be very effective. (ele)

didn't know that glyph worked on nature rituals seeing as i thought it was spell only. Never seen it work on ranger spirits either.
