Heater Size and Brand Preference

[OhioFrank28]

Just getting back into the hobby and trying to slowly upgrade old and antiquated equipment. I think I have decided on getting 2 Jager Trutemp 200w with an Inkbird IT-306a. Then I could set the heaters therm at 78 and use as primary control and use the inkbird in case of fluctuations.
My wife keeps our house at 64 F in the winters and I would be keeping my 75gal at 78... is 2 200w sufficient? My current Jager 150 alone, struggles.
I had been deciding between the Jagers, the BRS Titanium and Finnex Titanium. The latter 2 seem to be hit and Miss. The Jagers giant, but oh well.

I run a eheim 150 watt in 40 breeder sump of my 120.
House is 70 in the winter and 75 in the summer.
I do not run a heater in the summer.
