One thing I would add is to make sure you don’t buy something that is odd size/voltage/wattage in case a panel gets damaged and needs to be replacedReview all of Will's youtube videos on panels. Lots of good info and comparisons.
As for what makes one panel better over another? Here are a few thoughts:
Quality manufacturing
Customer satisfaction (reputation)
Longevity of manufacturer
Warranty
Power output under summer heat(temperature coefficient. Thats one stat what makes REC better)
Shading effect(another huge factor)
Cabling( some cheap panels skimp on the quality of the MC4 cables)
Install base ( What panels are solar companies using? They usually dont want unhappy customers).
Cost(Higher does not always mean better)
Availability( will you be able to expand later if needed)
And of course, how many panels are needed to satisfy your inverters volts and amps requirements
