[Google Pixel 2 XL ROMs, Kernels, Recoveries, & Oth] GROOVYJOSHCLARK:
OpenGapps is the most stable GAPPs I personally have found, and I test them all. It comes down to personal preference, and if you want to use OG with the built-in apps, or customize it yourself (as I do). I for one find they (GAPP packages around the net) are all outdated, as

none of them

can truly keep up with Google. The second Google updates an app, the GAPP package is outdated, and this happens quite often so good luck finding a GAPP that is updated and is customizable (OpenGapps), has the most up to date framework, and is as stable as OpenGapps. I haven't found any that meet this criteria (except for OpenGapps), and again, I test them all routinely across multiple ROMs. This is why I choose OpenGapps as their framework is solid, and thats what counts (we ONLY care about the Google framework GAPPs installs), everything else is customizable, or removable, or installable from the play store. The rest is add-ons you can add/remove using OG scripts (easy peasy to do). I posted this in LOS, but again, I dont care what you guys/girls use/do, but if you want my help, it needs to be something I can reproduce. I only use OpenGapps (for years) and NEVER have a hiccup, issue, or problem with their framework. The Google Framework is all that matters being up to date, the rest doesnt matter and is a prefence type choice. The apps will almost always be out of date (its difficult to keep GAPP apps updated when they change constantly), this is why you simply (and very easily) customize the OG install. Then you have nada to worry about with older apps, PLUS the framework will be as closely lined up to Google's as any GAPPs I have found/tested/used, this is because they (OPenGapps) packages are built nightly with changes. Not many other GAPPs are nightly maintained (yes, I know, OpenGapps are not always updated at night when there are no changes), but they are the most up to date framework I have found over the years. I am only offering this advice to show options for both GAPPs, not arguing with anyone as I do not care who destroys what anymore. Just be careful and review the details before choosing anything.

NikGapps seems to offer the debloater as well so again, personal preference, I have just found OG to be the most stable. NikGapps does support split APKs but thats not an issue for me, so keep it in mind when choosing GAPPs, you may need split-APK support, I dont so I do not use it. I personally have found the OG script is easier to use than NikGapps, but mileage will vary, I am a dev so I see things differently than most:

Please remember for GAPP choices for custom ROMs, I always encourage and recommend OpenGapps. I am saying this now, mainly to remind everyone that you can customize the GAPPs install using the natively built-in OG install feature (Advanced Features and Options):

"You can choose either the apps you WANT installed or the apps you DON'T WANT installed.

"Include" install: To select ONLY the apps you WANT installed, add the keyword Include to your gapps-config file. The installer will now install ONLY THOSE APPS you have listed in your gapps-config.

"Exclude" install: To select ONLY the apps you DON'T want installed, no keyword is necessary, because the default behavior is an Exclude install."

Not many users know or speak of this so I am bringing it back into focus. You can customize all but the aroma GAPP package, make it smaller, remove/add apps, replace AOSP, ETC., I know a few of you have asked for this recently throughout the taimen forums so I am adding it to the LOS 17.1 (10) ROM. This is usable on any ROM that needs GAPPs. There are a ton of advanced options that I encourage users to review so they can customize the GAPPs installation process to better serve their requirements (GAPP choices).

No MAGISK, no modules, nothing to mess with but the OpenGapps scripts so there are choices out there to use that comes down to personal preference is the only point to this message. Read the notes and make the best choice for your install based on what your criteria is, we all have our own. Mine is stable, works, no modules, nor anything difficult for newbs to use other than a one-time OpenGapp script to use. This keeps it simple and easiest for newbs.
