I live V4 Pro for certain things but I've been quite impressed with V4 Flash for coding. It's terse, to the point, tends to make few mistakes and is pretty fast.
When planning small-to-medium sized changes, I found that it was a little bit faster than GPT-5.5 (high) and produced equivalent results. on large changes its results were fine but GPT's were more thoroughly thought through. DS v4 beats the absolute pants off GPT when it comes tone and style though.
