IMO, maganda rin naman ang A/T, without the hassle of shifting gears while you fondle with your gf/wife/kabit/who-it-may-be, hehehe :D For offroading, better shift it to L1 a big no no in D. Plus the advantage over the manuals that the tranny is enclosed therefore, there's no risk of wet clutch.

On the other hand, in M/T you control the engines power. When and where to put more power or not. :D Plus maintenance wise, mas mura mag alaga ng manuals. :D

Final verdict: 50-50 basta't umaandar ng maayos at walang sakit sa ulo, "suportahan taka". 8)
