Awesome, simple question, quick answer.
See, the dvd's might be somewhat cheaper, but I like that I can watch them both ways. It's going on my wish-list, just bought the Stardate Collection in BR, but this should be my next 'to buy'.
Happy to help. One note is that the recently Amazon has been having the complete series on BR for around $100. I've been seeing the series on DVD going for around $80, so it's not too much more expensive. Good luck on your purchase!
