IMHO eg6 but both of those cars will be really hard to find at a good price.

EG6 is ftw.

-price they will be both fairly expensive for there ages. But EG will be a little more
-Reliability EG6 as it will be newer but both rare cars soo it will be hard to find one with high k's
-character both have equal amounts ooozing out of them.
-handling EG wins over EF forsure
-power EG wins over EF again
-Parts Eg will be easier
-insurance will be around the same for both
-mods EG will be easier as parts will be easier to source but both cars can be modified at anyway needed really. Can put pretty much any honda motor in any honda these days with conversion kits.
