There are those that are meshabeiach the use of these gemaros. Others not so much.
My take on it is pok chazi mai avid ama debar, what is the oilam doing. For some reason, most yeshiva gedoilahs do not carry them. The yeshiva I learn in has an extensive up to date library, but it does not include artscroll or the mesivta gemaros.
Personally, I have benefited immensely from them. Before each zman, I pay a chashuve kolel yungerman, to learn with me the chidushim in the back, which is a tamtzis of the “Reid” on each sugya. When I learn the sugya biyun during the zman, it goes geshmirt.
I’m told that there are others who do the same, but its begeder halacha vain morin kain.
Bkitzur, hachaham einav brosho; chap arain before the zman!
