I needed teeny-tiny sensors w/very long battery life for one particular application - using them attached to the backside of my cooktop's front plate to sense when burners are on and turn a led strip red to remind us we have burners (or the toaster oven) on. We (well, OK, I) have a bad history of walking off and leaving burners on. 
Very tight space and a bit of a PITA to get to, and the Aqara are very small (1.61 x 0.87 x 0.43 inches) and fit the space, and have long lasting batteries from the info I've seen.
In the end if I can't keep them on HE directly I'll use HA and HA bridge to bring them into HE (which @SmartHomePrimer has blessed). 
I can't find actual measurements for the Linkind...what are their dimensions?
Ah - found the Linkind dimensions on Amazon. So to compare:
Aqara: 1.61 x 0.87 x 0.43 inches
Likind: 1.62 x 1.25 x 0.56 inches
