Price and Conclusion

iPhone 12 Pro: from N 493,620.00
Galaxy S21 Ultra: from N 577,524.00

Both phones offer a great all-round experience and choosing one over the other might just come down to having premium build and a better display, Both have strengths and weaknesses.

As for software, iPhones benefit is that you get updates as soon as they're available and will likely be supported for a good number of years before it no longer gets them. Samsung is getting better in that regard - in terms of long term support - but you do have to wait until Samsung tests and releases its own versions of major Android updates.
