Looks like Trio64V+ and Virge/VX is highest end S3 supported unless I misread Nextanswers (https://www.nextop.de/NeXTAnswers/1737.html).
The S3's would be better than the Cirrus imho...

So,it's better to buy the trio 64/V2dx and use the S3 generic driver from NextStep Cdrom?Does it support colour mode with a decent resolution?

All it says is for generic S3 Supported Components: S3 732 (Trio32), S3 764 (Trio64), S3 764 (Trio64V+), S3 864 (Vision), S3 868 (Vision), S3 911, etc:
32 Bit Color Modes**: 1024x768 (4MB+), 640x480 (2MB+), 800x600 (2MB+)
16 Bit Color Modes**: 1024x768 (2MB+), 1280x1024 (4MB+), 640x480 (1MB+), 800x600 (1MB+)
8 Bit Color / Greyscale Modes**: 1024x768 (1MB+), 1280x1024 (2MB+), 640X480 (1MB+), 800x600 (1MB+)

For Cirrus GD5434
32 Bit Color Modes**: 640x480 (2MB+), 800x600 (2MB+)
16 Bit Color Modes**: 1024x768 (2MB+), 1152x864 (2MB+), 800x600 (1MB+)
8 Bit Color / Greyscale Modes**: 1024x768 (1MB+), 1280x1024 (2MB+), 800x600 (1MB+)

So about same color/res as Win3.1 with a decent driver....

Thanks a lot!I will try it.

Not necessarily, the general overview notes state:

• It is primarily intended to support implementations based on the S3 Vision864, Vision868, ViRGE, though it should also support many adapters based on other S3 products such as the Vision964, Vision968, Trio32, Trio64, & ViRGE/VX chips.

These chips have a similar 2D core but the Trio64V2/DX, ViRGE/DX, and ViRGE/GX all share a newer 2D core, which the driver might not be compatible with. Unless someone has tried the newer chips and verified that it works with this driver, you should stick to the supported list. The "best" out of that list is a Trio64V+ (S3 765), essentially a Trio64 with video overlay support (video scaling and colourspace conversion).

Agree !! The Trio64V+ is the best choice IMHO

Can I check the compatibility with 86Box?

Also,I found this:https://www.nextop.de/NeXTAnswers/1818.html
Does that mean that cirrus logic gd5434 is supported?

Yes, it would appear so. In terms of functionality it is roughly equivalent to the S3 Trio64.

That would depend on the accuracy of 86Box's emulation, best ask that on the 86Box discussion forum (unless someone here knows for sure).

Yes...I may try to find someone to borrow me one.

Now,I have a new question.Does Nextstep support Diamond stealth 64 vram or dram version?Also,does stealth 64 is supported by win 3.1?

Wikipedia says the VRAM version uses an S3 Vision964 while the DRAM version can be a Vision864 or Trio64. All 3 should be supported according to the first link @Horun posted.

Nice!I think I will go with a stealth 64 vram then.
