In my case, the option is clear: VHS.
Once image and sound quality have reached a certain point, any improvement is a moot point for me.
I usually watch things once, so recording is much more important.
The last time I checked, VHS was both cheaper and could record for longer.
Besides, I hate the access controls on DVDs. Once I buy something I should be free to do what I wish with it, short of breaking the law.
