Oval cut help

I've decided that it's unlikely BTD will do an oval amora by the time I'll need/want one so I am researching other options.

I like the wider oval style 1.3-1.45 ratio, while I'll never try to pass it off as a diamond I'd like it to look as similar to a diamond as possible.

Any recommendations as to which brand has the best cut oval? I'm looking into the supernova, neo, diamonna, etc.
