Both are really good looking cards...my preference is for the 1914 since as we all know by now 1915s are glorified reprints
Dean's is know to have higher prices and you may get one cheaper if you can wait at auction.
That same 1914 card sold for $261.60 in 2017, $539.99 in 2018 and $930 in 2022.
Good luck on whichever one you choose.
