test is test. there is no difference between the 'test' in test cyp and the 'test' in test prop . the only difference is the oil and the time of absorption, test cyp is slower absorbing and requires less frequent pins, test prop is faster absorbing. thats the only difference. results will be the same over the big picture . test prop will be faster acting, but also faster out of your system as well.
you can always front load test prop for the first 2-3 weeks while taking test cyp as well, to get the benefit of the fast acting prop. then stop the prop and just continue with test cyp for the convenience factor.
Rather than front loading, i'll just use cyp, that would be better.. how long should my cut cycle be if i plan to cut with cyp??
