To review the packages you need first to be proficient at them. And there's problem number 1... most cad packages have a long learning curve and once you are used to one it becomes 'hard' to use something else.
Second problem is you actually need to know how to do board layout. Reviewing a cad package based on a 5component single sided board is nonsense. any cad package can make such a board. the power of the cad packages only comes to light when you start torturing them with things like realtime DRC , rubberbanding , push-n-shove and all the other tedious timeconsuming crap that humans generally hate but omputers just love to do.
And then you end up at problem number 3 : once you are used to a cad package that does a lot of the tedious crap any package not handling the same crap will be considered inferior and shot down in flames. so you invariably end up with a reviewer that is biased.
it is the same scenarios as someon who learns mechanical drawing and has to do it with crappy pens and chinese ink on vellum. a bit later he upgrades to rotring pens.. ah life is better now. then he gets a real drafting table. wow ! great, then he gets a simple vector drawing program and a pen plotter. now we are really jamming... and then he gets aPC and autocad. Wow. welcome to the future and a bit later he is introduced to a workstation running Solidworks coupled with a 3d printer ....
you guess what will happen at various stages ... by the time you are at solidworks anyone suggesting rotring pens as 'state-of-the art' will get them jammed up their nostrils , the vellum used to make papercuts in the webbing between their fingers and get the bottle of chinese ink poured over their head.
the same goes for CAD reviews... you CAN do a meanunful review between Solidworks and Autodesk inventor. You can do a meaninful review between Mentor and Cadence and Altium.
You can NOT do a meaningful review between Kicad , eagle and Altium as you are fighting in a different ballgame. (Kicad being a contraption made by programmers that have no idea how a board workflow works, eagle being a long standing player in the PCB editor market but stuck at the pen-and-paper replacement with some tools thrown in and Altium doing stuff the kicad and eagle programmers can only dream off)
I would be a bad reviewer for eagle and kicad since i have a certain level of expectations form a PCB tool. and both programs would fall grossly short of even the basic stuff i want. Nevertheless they may be viable programs base don other criteris ( needs to be low cost , doing only 5 component boards , thru hole , one board a year. etc )
in short : it is very hard to de meaningful reviews.
