well I have both laptop lunch and easy lunchbox and this summer I got the Planetbox. I LOVE LOVE LOVE the planetbox. Sorry to make your decision harder. I wish I had just started with the planetbox. I love it because it is not plastic, can go easily into the dishwasher. The laptop lunch has "better" plastic but it is still plastic and there are a lot of pieces (that said I used it for 3 years). I use the easy lunchbox in a pinch but I found the sides shatter on occasion (just little chips) and the plastic gives me pause (we purged almost all plastic out of the kitchen and I know not everyone is so into doing that).
