Any thoughts on wireless repeater TP-Link RE450?

It seems to be the first AC1750 repeater in the market. In my country(Singapore), it is priced pretty closely to other brand's AC1200 repeater. I am using a Nighthawk X6 R8000 btw.

Here are my findings -

>1000Mbps
TP-Link RE450 (AC1750)@ $139
Netgear EX6150 (AC1200)@ $139

<1000Mbps
Netgear EX6100 (AC750)@ $89
TP-Link RE200 (AC750)@ $59
Asus RP-AC52 (AC750)@ $119
D-Link DAP-1520 (AC750)@ $59
Prolink PWC3703 (AC750)@ $63
Sineoji WRE750E (AC750) @ $69

Can't seem to get the price of Linksys...
