No laughting please

I was ready to resurrect an oldy when an acquaintance of mine was throwing his away so I picked it up just in case it was worth something.
Since I do not need 2 slowpokes but one will suffice

So, who should stay alive?
On my right, we have Tyrannosaurus rex, aka celeron 600 mhz, 256 meg ram
On my left, we have Triceratops, aka pentium II 333 mhz, 512 meg ram
both loaded with the latest OS aka windows 98!
Just in case some of you would wonder if my intent is to overclock the monster

Hey, you can always ship me your antique if it's better and you can't bear the idea of having such things still around!

Can't wait until I see your recommendations!
