Those, like about 98% of what you find searching for gel batteries, are really AGMs of a sort. The charge voltages are WAY off from what a gel uses.
There are 1001 different versions of Chinese batteries to be found for much less than Deka gels and I really have no idea how good any of them are. Those would probably start an engine just fine. YMMV on how long they last. If you want to go AGM, Sams Club sells private label versions of the very same Deka AGM batteries as West Marine for half the price. https://www.samsclub.com/p/duracell-agm-deep-cycle-marine-and-rv-battery-group-size-31dtmagm/prod3590232?xid=plp_product_7 They are also about 100 AH, start engines just fine, and cost $10 less.

Thanks, Joe. I was looking at something like this for my two house batteries. Amazon.com: Mighty Max Battery 12V 100AH Gel Battery Replaces Solar Wind Deep Cycle VRLA 12V 24V 48V Brand Product : Health <https://www.amazon.com/gp/product/B079YL15T2/ref=ox_sc_saved_image_2?smid=A33N703ELCFX8U&psc=1> & Household What do you think? Also, do you use the same batteries for both house and engine starting? I know the starting battery will also need to be gel for charging purposes, but all the gels I’ve seen appear to be deep cycle, and not designed for engine starting.
