I own both of these lenses and have tried them on my GH1. Both are great lenses.

The Vivitar is a larger, heavier lens. At full extension, it is about 2.75" longer than the Canon. Of course, that's largely because it's a 90mm lens. The longer focal length will allow you to be a bit further away from your subject, which is nice when doing macro, but it will also make it a bit more difficult to hand-hold stable, meaning you'll have to use a faster shutter speed to keep things sharp when shooting by hand.

The Canon requires the tube to get to 1:1, but that can also be an advantage if you just want a 50mm lens for regular shooting since you can remove the tube and it's a bit more compact (but still larger than a regular Canon FD 50mm lens).

Which is better for non-macro use depends on what focal length you find useful. A 50mm lens has a crop factor to 100mm field of view, making it a potentially good portrait lens. The 90mm is like 180mm, making it more of a telephoto. Which interests you more?

Here's a photo of the two (both fully extended) next to a Canonet QL17 GIII, which is about the same size as a GF1:

These will be even longer, with the mft-FD adapter.

Here they are, both as small as possible:
