Stars Is more User friendly+Prizes are that much bigger. Now the downside to Stars Is the massive fields+landmines that a player must make It through to get to that "Massive prize or even top 3". The players just seem "That much harder/better". Also on Stars the daily CC free-rolls+SMC+Over all free-rolls+CC league+PSO league/School+Big Bang (Tickets), need I continue?
Now 888 as stated, lack of "free-roll selections" (As compared to Stars private ones)+lack of league (CC league or any-sort of 888 equivalent league to match Stars), the only free-rolls they have are those "Ticket ones" (Which have like 5k+and are hypers or something like that). Now positives to 888 the games are softer and yes (They do have some decent prize pools also), yet the decent prize pool games are "That much more expensive to buy Into". Thing about It, would you rather buy Into a $215 with say 1k players for X amount of $$$ winning say 40k-50k, or would you rather win the Sunday Mill for $150k but vs say 10k players. Also since the fields are smaller, that would mean that getting to ITM (Is also smaller).
Don't get me wrong, I myself see ($$$$) as that, and 40-50k Is nothing to scoff at, but you'd have to win It 3 times to equal one score of the Sunday Million and you'd have to pay a higher price tag to enter (That said game on 888). Yet the site over all Is softer vs Stars.
Now as others have stated the site"IMO Is ugly, I have no other way to put,lol.
