XSLT/XPath have evolved since XSLT 1.0.

Features are now available like key (index) to greatly speedup the processing. Good XSLT implementation like Saxon definitively helps as well on the perf aspect.

When it comes to transform XML to something else, XSLT is quite handy by structuring the logic.

Appreciate your input, but if you haven’t actually tested the VSCode integration, it’s hard to compare. Reading a feature list isn’t the same as using the tool.

Not comparable.

I did test VSCode and IntelliJ on agentic, MCP, and IntelliJ is for the moment far behind.

Is your affirmation based on a testing of both plugin? I'm genuily wondering the plugin quality as IntelliJ plugin is still in beta and the VScode one not

VSCode is really the primary platform for AI/agentic plugins, receiving priority over other IDEs such as IntelliJ, this is understandable as it is free, supporting many languages, and really good.

As a long-time IntelliJ user, I’m beginning to question whether it still makes sense to remain on this platform.

Perhaps I’m too impatient and agentic plugins may reach parity on IntelliJ within a year but a year is quite a long time to wait in this really fast-evolving landscape.
