It's always good to see this trilogy get some love, it really does feel sandwiched between PS2 PES, and the early PS3 installments which kept a similar formula, and the FOX Engine ones. I find PES2011 to be the best simulation, while PES2013 is the better video game for most people, though PES2012 was the only one I actually bought, early on I regretted that because players felt so light, shooting was unsatisfying, and defending felt impossible for a younger me, but it was the only one I owned until I bouth PES2015, so in 3 years I got the hang of it and learned to love it, especially since it introduced a feature I love nowadays, FUMA. I don't think you're missing out by not playing it more, because PES2011 and PES2013 are superior, but if you do ever get back to it for another go, what I recommend is to avoid pressing, just do the hold up play/jockey and let go of the button when you absolutely need to try a tackle, or if it's an easier tackle to get right, the shooting also grew on me because of how unpredictable it is, and FUMA... feels great here, I recommend it.
