Help me pick my next Slim LP phone

Hello Slim ROM fans. I've got a tough choice to make. I currently have a Galaxy S3 (i747m) which is running Slim LP 5.1.1 beautifully. I love this ROM. I recently flashed the S3 back to the stock touchwiz and instantly missed the Slim ROM. It has become a major factor in the purchase of my next phone.
Anyways, my contract has expired and I figure that since I am going to keep the same plan that my last contract had, I might as well resign and get a cheap / free upgrade to a new phone. My biggest problem is which phone to pick...and most importantly, make sure there is a Slim LP ROM for it...or at least in the works. I have tried Slim Kat and Bean but I prefer LP. Also, installing Kat or Bean is difficult now because any new phone comes pre-loaded with the latest bootloaders which apparently will not boot the older versions of Android, so I'm pretty much stuck with Slim LP....not that I mind tho. So here are my choices.

Galaxy S4 (i337m)
Galaxy S5 (not sure which model exactly, but its from Fido so Canadian version Im sure)
LG G3 (D852)
Sony Xperia M4 Aqua (unknown model)

So what do you all think? I am biased towards the Samsungs for the better contrast screens (super AMOLED) and extra buttons so keep that in mind.

Please help me pick a ROM based on my criteria...

Hi folks,

I hope this isn't a faux pas. I understand we're not supposed to start religious wars about which ROM is the best. So let's not do that. But I could use some advice on the pros and cons of the different options open to me. Here is my situation and success criteria:

1. My T-Mo M919 is currently running an old SlimKat Android 4.4.4 from August 2014. I'm on the MDL bootloader and NB4 GSM modem at the moment. It's running mostly OK, with some camera freezes, some issues with battery drain when Bluetooth is on but not connected to a paired device or in use (wakelock prevents deep sleep... possibly app related?), and I've noticed the ATT Visual Voicemail app, when used to listen to a voicemail, kills subsequent phone call audio/microphone requiring reboot.

2. I've gotten used to Android 5.1(.1) on my tablet and I'd like to make the jump up to Lollipop. So I'm mostly looking at ROMs that are either 5.1 or 5.1.1. However, I'm considering as an outside contender just getting the OH3 firmware for the M919, doing the double flash to get me all the way there, then rooting and freezing Samsung crapware.

3. My criteria are: STABILITY. I don't need a lot of customization. I just want the thing to work. This includes being able to use the camera without it freezing, and being able to use my visual voicemail app without it nuking the phone function of the... uh... phone.

4. I use the phone mostly as an email / texting / forum-browsing device that a few times a week is actually used as a phone to make voice calls. I occasionally tether other devices to the phone's wifi. This needs to work without a hitch.

5. I use Bluetooth to pair with my car's audio system and I need that to be smooth. I recall in the KitKat days there were lots of complaints about glitch pairing/audio. My Slimkat has worked well with the car audio (a late model Toyota); no glitches. I want something that will have stable Bluetooth audio.

My current planned front-runner is the 5.1 GPE ROM by Danvdh. It seems quite stable from reading the thread.

Team Radium's ROM also looks promising.

On the AOSP side, the relatively pure AOSP recently posted by AntaresOne looks good. And I've run Dirty Unicorns before, in the 4.4 days before I moved to SlimKat. That was a good experience. And of course I hear the Slim folks are rebooting so SlimPop or whatever is an option.

I'd like any good direction, focused on stability rather than artwork or customizability, that will help me decide. Thanks!
