Choose nRF52 or 51?

[JS]

Hi, There are some older comments. Since situation is changing fast and I am un-sure if these comments are out-dated or not.

1. ROM size. Some comments said 51 is small and the space left for user code (after factory stack) is 'small' How 'small' is it nowadays? Roughly how many line of C code space left?

2. 'Less bug'. Some said 51 is older and less bug. How is it now?

3. For multiple chips in 51 and 52 family, which specific part number chips, for 51 and 52, are recommended for newly started development work?

Long long time ago, when BT chips first came out, they have their fair share of bugs, naturally for any new chip. This time, I plan to choose a stable (less bug) one.

nRF52 gets my vote here. I am sure that most of the people who are a part of the cv writing service team will select this thing, as well. I know that my mates are going to have the same opinion as me, so that satisfies me.
