To each their own.
I personally put in 200 games between 2 franchises so far and been having a great time with it.
The gameplay for my games are close to even and real stats, scores are not crazy unbalanced. I find that hitting is harder overall but makes it more worthwhile, along with more risky if you pinch at the wrong time. The 1 tee green goals have lessened but I still get them in (this is due to the nerfs they made due to over usage in Online play).
Winning the puck in the corner, its hit or miss for me. I tend to try and force the player to dump it along the boards in hopes one of my players get it. If I can get a player to come down and help it tends to not always work and leaves a opposing player open to get the puck and make a pass out.
Goalies overall, from my personal game experience ( my team GAPG is a 1.89, both goalies with a .904 or higher and sub 2.00 GAA), thus removes the whole 25-8 shot games where you lose 3-2 (which was an issue for so long). You have to work for goals in this game, as you said, the ice isn't open for you to take shot after shot. I rarely hit my player unless I'm shooting into a lot of traffic (then its a toss up).
Hitting I find is a lot more risk or reward, where you can make a good hit but then if its a unwanted pinch can leave you susceptible to an odd man rush. Stamina is more important in this game (where you need to actually utilize it to help gain more scoring chances), which I have started to play a true experience with dumping to make a change or a dump and chase.
I have learned that if you play along with the AI, then there are far less instances where the players are out of place which has allowed me to be within the top 3 in both seasons of my franchise in team defense (this is a huge update over last year when I would have no idea what it was doing 70% of the time).
Plus, the slower speed of the game, puts in on par to what the speed would be in the NHL (which is a huge change from the arcade style it has been for years).
I have heard there is issues with line adjustments if you change coaches but I have not experienced it myself, also some of the contracts, morale is still not working (but hasn't ever really worked - which is why I play with it off).
