Yes the mk5 is definitely much more aggressive looking, but if you look at the mk6 celica they both followed a very similar design style. Also cars back then in general didnt have an aggressive look. Just look at how 'happy' Zeds look even when they were styled years later, in basic form hardly aggressive either Cars generally didnt have an aggressive look in the early 90s swooping lines was all the rage, look at the 300zx, RX7, GTO, R33 etc.
The NA version was decent enough but not a patch on say the M3 at the time, but thats why the TT was around, which was and still is a legendary engine, fully forged straight out the factory
