you'll get many opinions on forums. you really need to go out and try some EPs for yourself at a star party, club meet etc.
btw. you have a scope on a tracking mount. no point getting widefield eps if they are going to be dedicated planetary eps as a planet will only ever occupy a small portion of the centre of the FOV. But 8mm is still on the low power side for planetary viewing in an f/6. I'd go more for 5 or 6mm. or 10-12mm barlowed. 12mm UO HD ortho in an Orion Deluxe barlow (best barlow for planets IMO thanks to internal baffling) would be superb.
