The big thing is your house and there seems to be no way to predict why tiny difference in the design of some adapters work good in some houses and work poorly in others. When it comes to signal strength 2.4g will penetrate wall and floors much better than 5g so you should stay with that. There tends to be a optimum antenna gain and radio power level which is why all manufactures tend to look the same. What they many times do is lower the radio power when they increase the antenna size to not violate the standards. Mostly what you want to confirm is both transmit at the legal maximum power including the antenna gain. Still the FCC only cares that the equipment does not violate the laws they don't do any actual test that show which work better in real life. The tplink is also someplace in the FCC database and if you dig long enough you can actually get the numbers for the antennas. I will suspect there is very little difference in the DB gain between the 2 adapters you have listed here antenna. Means if you really wanted to you could connect external antenna that are used to connect to internal mini pci cards.

One of the interesting things I saw on the internal photos is this device uses industry standard antenna connectors. I am sure they do but so far I have not found it other than comment is it is a 'printed' antenna whatever that is. Was hoping the outright told the antenna gain for the internal antenna. So in this case I got a more interest than normal and went and dug though the FCC database for the linksys device Look at how well cellphones work and you never see antenna anymore. Well designed antenna make much more difference than the size or if you can see them.
