Evra is aerially better when attacking and defending, set-piece threats yeap he scored headers, better pace and more agile. Unique trait -- his ability to improve, adapt and achieve quick growth in football ability is also freakishly impressive from a slower and weak in strength when defending on the ground and air to a quick adaptable monster defense in both plus adding aerial goals to his arsenal later on.
They are on par in possession play, supporting teammates, dribbling, one-twos combination of passes, short passes, ball-carry, running into box, off-the-ball movements, marking and one-on-one defending
(tricky wingers eg. Lennon is Evra's kryptonite though).
Irwin is overall better and have plenty more to offer -- greater consistency, can take all set-pieces, scored with FKs and Penalties, better shooting, better at crossing and final delivery, better long ball passer, good "positional" defending
(doesn't get caught in position), effective set-piece defending
(similar to Blind in that sense), good weak left foot, scored with both feet, and ability to play in multiple positions LM, RM, LB, RB.

That said,
there is this "
fun-ness" and "
craziness" when it comes to watching Evra play, it often makes you smile, while with Irwin you just can't help but feel "
in awe" admiration and it feels like seeing "
machine" watching him play due to his impressive level of repetitive consistency and reliability in how he play -- ruthlessly effective and you know what to expect, similar to watching Ronaldo's "
terminator" football nowadays compare to younger Ronaldo that played a more
"unpredictable" and "
crazy fun" football.
