First of all, welcome to GBAtemp! Second, please read
the rules, don't ask for warez stuff.
With that out of the way, Tinfoil shops can be unreliable at times so other than being somewhat convenient (i.e. you can download directly to the console) I don't really see a point in using those shops? So far I've managed to live without them and I'd highly suggest that you consider doing that as well. I usually download the files to my PC from certain trustworthy websites and, once done, connect my Switch to the PC and install them with DBI. I'm yet to run into an issue to this day.
As long your CFW setup is up-to-date and updates do not require firmware higher than what you're currently on, you should be good to go. I don't use pre-made packs like HATS, I just keep my Atmosphere, hekate, sys-patch and DBI files up-to-date, followed by any other sys-module and homebrew app that I may use as well.
