I recently purchased and put together the A Frame picnic table.
This is a well designed table in terms of ease of assembly.
Pro's- The A-Frame design makes this a very sturdy table -  screw holes are predrilled and come with the screws in the holes so everything aligns perfectly. The A legs and braces slide into rails on underside of table so there is not really any technical assembly. The benches slide onto the A frame - no drilling required.
Con's- Do not see one - unless the grayish color of the table and benches bothers you. (tablecloth fixes that)
SUGGESTIONS for assembly: IT IS A TWO (2)  PERSON JOB. You will need an electric screwdiver. Elevate the table to put it together (saw horses). 
My wife, friends, and I really like this table. Again, it is a sturdy table. My larger friends sit comfortably without a wobble. It weighs about 90 lbs so 2 people can move it easily. It was a great purchase for us as we entertain cookouts evey weekend.
