I guess its time for my 2 cents

My first rifle was a TikTac in .308 win. Great gun out of the box. Was getting groups .438-.401" at 200m with 150grn Federal FMJBT. I picked up a Remington XCR TLR in .308 a month later and I had groups of .155-.003" ( yes .003", they all went through the same hole!!!) @ 200m with the same batch of 150grn Federal FMJBT. Needless to say I sold the TikTac and spend the money on making the remington even better.
Both are great rifles, but if you are looking to make them better than stock I would go for the remington 700 as it has much more aftermarket following.
