For me, no not really. Most people go Real or Barce and pressure the hell out of you. There's no point trying to play possession football to tire them because I think the fatigue system is broken. Played a guy who went as Real pressured the hell out of me all game...I didn't pressure once and my players were wrecked whilst he waltzed around with Ronaldo. The trouble is you can counter teams like this if the connection was flawless, but because of the lag it makes it practically impossible to match a pressure abuser.
Those players who successfully pressure you experience the same lag that you do. Don't make excuses. And if pressuring gives such an advantage, why don't you do so? If pressuring a team with Barca and Real while waltzing around with Ronaldo is so successful, why don't you do it? Maybe you are not as good at it? So you sucking at handling pressure is the reason why online sucks? Then don't play competitively because at top level, elite players uses teams like Real and Barca and usually tend to pressure. If you cannot find a solution to that, then work on your tactical knowledge; during such situations, precise long balls, fast forwards, timed countering, slick one-twos and impeccable first touch is what you need. All because YOU are not adept at such skills does not mean you should think so selfishly and label the online experience as 'not really good' all because YOU aren't that good at the game. Don't make excuses for your losses; learn from them and over time, you will slowly get better and adapt to managing yourself much better in those stressful and pressuring situations.
Btw, based on my experience, this is the most lag-free PES online ever and even games with players from other continents is relatively smooth. But that is just my experience.
