How do you find your sales on Amazon compared to eBay?

I'm not liking how I can't do variations (or it is limited to size and colour) and I have to list it one at a time. I just got the jist of bulk listing using excel but its a bit time consuming since I have to upload my own images to my server and then copy and paste them one at a time to the spreadsheet.

So far no sales, though I just started and I have still have a ton more listings to do.. Yay going to have a borring draining week this week.

And omgosh I have to buy my own barcodes to list items and each variation need its own barcode..
