Shinji, Rei, Fuyutsuki and Hyugaa are the same as the 90's, the rest were replaced.
I've always have a soft spot for Shinji's VA, he managed to portray him very well. Rei always sounded too... Lively. Not that she does not deliver her lines in monotone, but in that she lacks that soft-spoken tone the original has.

The new Misato I can grow accustomed to. She is different to the VA from the Rebuild dub. She is lively, but at all times. The serious lines of Misato sound forced.
Asuka... Well... She tried... Latin dub has this horrible tendency to have Asuka speak with a German-ish accent. IMO only the original one did so reasonably good. This one sounds like someone covered her nose while she was speaking on top of having to fake the German accent.
The new Ritsuko was a nice replacement. She was originally voiced by an older woman, so she sounded collected and wise at all times, but the voice did not match the character's age much. The new one sounds OK, and much younger.
New Gendo I love, he sounds not as deep, but still menacing and commander-ish.
New Kaworu has the same problem as Rei. The original VA gave him this ethereal, otherworldly tone that really matched the character. This ones sounds too lively.

Now, for the dub itself.
Its great! All the background technobabble is there, and the editors did a great job matching lip movement without altering dialogue too much.
Fly me to the moon is gone in here too.
Pen Pen is not referred to as a penguin, just a "hot water bird".
SEELE is pronounced properly. The original one used "sea-lly"...
Evangelion is pronounced Evan-Jelly-on... I prefer the strong "G" /x/, but that's just me...
AF Field is translated both as "Escudo AT" (AT shield ) and "Campo AT" (AT field)... The AT Shield thing stems from the original dub, I dunno why they used that one. But alternate between the two, even within the same chapter and just lines apart, is just madness!
Some lines sound mixed up. Like they spliced two different takes together.

EoE... Well... They made some questionable choices:
Key lines:
Kimochi warui: how disgusting.
Shinji's' "I'm so fucked up": I'm so disgusting.
Gendo's silent line: silent (thankfully)
The Misato-Shinji scene in the elevator was OK until Shinji said some weird lines, basically making it sound like "I'm not worthy of piloting the Eva because I have hurt people" instead of "I can't pilot the Eva because I will hurt people". Also "you are a stranger to me! You can't possibly understand me" instead of "you are NOT me, you don't understand me". Misatos lines after that are very weird-sounding, too.
To be fair, the pseudo hallucination in Lilith during 3I is confusing, but the dub made it worse. Some things were translated literally and as a result, they make little sense in Spanish or even when in context with surrounding lines.
The Shinji-Asuka scene in the kitchen... Awful... Just awful... Shinji's "only you can help me" is, for some reason, translated as "you are the love of my life" .
The Rei-Shinji-Kaworu exchange at the end of 3I is faithful, but sounds forced.
