Both are very good ssd's. Normally I recommend Samsung first. However, at this point I would say purchase the one that has the lowest sale price.
Tom's Hardware usually has a daily deals link on their home page to Logic Buy which shows the lowest sale prices for pc products. Logic Buy has a web page just for drives that are on sale. Here is the link:http://www.logicbuy.com/categorydeals/computers/hard-drives-ssd
Sale prices change daily and include newegg and Amazon among other vendors. It pays to be patient and check every day for the latest deals until you see what you want.
