methyl cyclopentane would give faster reaction as the halide substitute the alpha hydrogen the carbocation would be formed easily as there would be less steric crowding in compare with .Isopropyl cyclopropane 
In  there is isopropyl that hinders the speed of the reaction and therfore,  the reaction would be slow hence.Isopropyl cyclopropane 
As SN2 reactions are inversely proportional to the steric crowding.
