Hm, interesting position!
I worked through about 15 lessons of RTK, but ultimately have found Wanikani more useful to me personally. It was exciting and fun to be able to absorb so many Kanji so quickly, but because I wasn’t learning readings or vocab alongside each kanji, I wasn’t getting a good idea of how the kanji actually work in practice, nor was I able to read the kanji. Additionally, some of the earliest Kanji taught in RTK are chosen for simplicity, but are pretty obscure, so I was getting frustrated being unable to apply them to real life. I did, however, appreciate reading the foreword and the method, which stuck with me and I still apply to my kanji learning.
That being said, I do have some friends who used RTK primarily and have had success. They supplemented by adding their cards to Anki, and making sure to include readings and common vocabulary on the cards.
I think whichever method you decide to go with, the most important thing will be showing up consistently and doing the work. So in that sense, going with the study method you feel more positive about/have more fun with is the way to go! I cannot say I have always been having 100% fun on Wanikani over the years. In fact, much of the daily study has been a slog. But there are a few things I love about this system that are the reasons I have chosen it: I like the quirky writing style, the encouraging level up emails, the community, the gamified leveling system, the stats, etc. All of those features keep me engaged when it’s difficult to go on.
And in terms of the actual Japanese learning method, I love the integration of learning Kanji, Vocab, and radicals at the same time. Once I finish a level, I can confidently recognize and use the kanji in real life because it has been enforced so well. I was amazed doing 17 levels or so before moving to Japan, because what had been indistinguishable a year before became recognizable.
So yes, for me personally, half learning each character in RTK was too tedious for me, because having to go back and relearn readings and vocab in the future was intimidating.
BUT. Go with something that you find enjoyable and interesting! If you stick to it, even if you slow down, even if it gets hard, you will learn to read Japanese. Keep engaging with what makes you excited and draws your attention 
edit: if you choose to go with the RTK route, creating your own mnemonics for readings is not hard to do and will be super worth the effort
