I haven't been to Vegas, so I cannot compare based on personal experience, but I have been to the Casinos in Detroit, and if you're just looking to gamble, Detroit is OK...not bad, but not really good either, and don't expect the glitz (or service) of Vegas or even Atlantic City.
If you're into slots, then they're fine (Don't go on the weekend's though), but for tables they always seem to be crowded and over priced. (Very few, if any, $5 and $10 tables, usually $15 and up)
I've not been to the Windsor Casino, but my father-in-law loves it.
I have been to the Slots at Windsor Raceway...again, if you like slots this place is nice (no tables at all). Plus (if you cash in American $$$) you get about 50% more playing money. Usually exchanging $1.50CND for $1.00US. (Although when you cash out the conversion goes back the other way)
Added bonus at the Raceway, if you're not having a good night, you can always go and bet on the Ponies. 🙂
Again, I've not been to Vegas, so I'm only comparing to what I've seen on TV and heard from others.
