The 7100 any day. Why?
- Faster in stock form...although most 7100s were the 66 Mhz version, same as the 6100/66, there was also a version which used the 80 Mhz PowerPC 601, which was never offered in the 6100.
- More RAM slots, the 7100 has 8, meaning its cheaper and easier to upgrade than the 6100, with its 2.
- 3 NuBus slots AND a PDS slot, in comparison to the 6100's single PDS slot that requires a right angle adaptor or G3 upgrade, and no NuBus slots unless you find the very rare 601 PDS to NuBus adapter
The King of NuBus PowerMac Hill, however, is the PM8100, which has all the advantages of the 7100, but in a tower case with an extra drive bay, and was offered in even faster versions, with speeds starting at 80 Mhz, and the faster versions having 100 or 110 Mhz CPUs. I've owned two 8100s, an 8100/80AV and an 8100/110AV, and absolutely loved them both, they were great machines. That said, if someone offered me a 6100, I'd snap it up in a heartbeat - I'd love to get back into the 601 PowerPC game.
