The new Lionel Barn is $149.99, The Menards is $89.99. Now with that said Lionels is molded plastic, Menards is some type of compressed paper/hardboard. Not taking sides but just pointing out the differences. Can Lionels fade due to sunlight or other light possible, can Menards, I have not heard of it happening but would not count it out.
The bottom line is, are you willing to pay almost 60 % more for the one from Lionel ( using MSRP not counting Menards 11% coupon as most of us can't really use them or discount from some of the dealers on Lionel products )
Personally, I like Menards barn better as it has more detail added to it, but will it last as long as Lionels, who knows, and at my age, it really doesn't matter to me, as I figure it will last what I have left on this earth.
Bottom line you have to decide which is the best for you and if your willing to pay Lionels higher prices. Once I heard Lionel bought the molds I said to myself, yeah and they will come close to doubling the price to recover their investment meant and to get the profit margin they need to get it to the consumers via the distribution system they use seeing they have put a middle man between them and the hobby shop ( other than about the top-selling 10 I believe it is )
