Yes, EasyTutu incorporates many dialog.tlk changes and other changes which are subject to the creator's decision, and, personally, I don't care for them, but an average user won't notice much difference.
heh... i try to fancy myself a more-discerning-than-'average' user (i tended to be most obsessive about seamless mod grammar & spelling, and the continued development of de'arnise romance, unfinished business and virtue, during my last major lurking period), but the sad fact remains that i have yet to complete a more-than-vanilla playthrough of any installment of BG! and even though i dabbled in proofreading and playtesting shortly after i started... 'collecting' mods (which at least gave me a feel for the NPC-building work of a few ppgers and g3ers), i still have countless comparisons to pose...
i would mostly like to blame iwd2 for holding me back at precisely the wrong time, dazzling me with its 'roll-an-entire-3e-party-from-scratch-and-then-plot-out-the-perfect-triple-class-combo-for-each-member' options - even while my soul was starving for diverting sidequests and developing relationships with NPCs (to say nothing of the utterly silent party members)... if i had ever been a modder in the past i would have thrown all of my dedication into icewind-gate conversion/assimilation, but alas, this was apparently not in the cards. my biggest weaknesses in any form of gaming are my addictions to starting over and doing nearly anything to avoid The End...
so, um, yeah. enough about me - until my next Mood
