MacOS Recommendations for Mid-2014 MacBook Pro 15” 11,3 & Late-2012 iMac 27” 13,2 using OCLP 2.4.1

New to the group but happy to have found it! Looking for advice/recommendations for my iMac and MacBook Pro using OCLP based on personal experiences (if you have the same model as me) or general advice from experts in the community to help a smooth & easy transition from a newbie using MacOS Big Sur 11.7.11 with OCLP 2.4.1 to upgrade.

Which of the following should I upgrade them to between:
- Monterey 12.7.6 (07/29/2024)
- Ventura 13.7.8 (08/20/2025)
- Sonoma 14.8.7 (05/11/2026)
- Sequoia 15.7.7 (05/11/2026)

I’ll include all the stats of the models so you have full picture:

IMac 13,2 (27-inch, Late 2012)
Processor 3.4 GHz Quad-Core Intel Core i7
Memory 8GB 1600 MHz DDR3
Graphics: NVIDIA GeForce GTX 680MX 2 GB
1.12 TB Fusion Drive

MacBook Pro 11,3 (retina, 15-inch, mid 2014)
Processor: 2.5 Ghz Quad-Core Intel Core i7
Memory: 16 GB 1600 MHz DDR3
Graphics: Intel Iris Pro 1536MB
512 GB SSD

Thanks Everyone☺️
