Well. I will give you my opinion: NEITHER
Those will be either Starting or MARINE/Deep cycle (Almost starting) batteries, Not at all the best thing for RV use as house batteries, Good for ENGINES though.
If you have room. then get TWO GC-2 batteies (not all Costco Stores stock these, Most Sam's do) These are roughly the same footprint as a G-24 (the first one you listed) but are TALLER.. They are also six volt so you wire them like this
-{bat}+=-{ery}+12V to make one BIG 12 volt battery (220 amp hour +/-10 AH)
The two of them together still = one 12 volt battery (Size 4D or 8D depening on + or - on the other line) so you charge them the same, You treat them the same (Save for inspection and cleaning and adding DISTILLED WATER to aboutr 1/8 to 1/4 inch below the filler tube from time to time) and they last and last both per-charge (yoru Group 27 is like 95 AH, group 24 about 75) and with proper care Years and Years before replacement (mine went 9 years).
But alas only if you have the room
If you do not have the room for two, Measure your battery box and get the largst one that fits.
