Graphics :
Tomb Raider could support 320x200 and 640x480 in 2D software mode and 640x480 with a supported 3D accelerator. The game on the PS1 almost certainly used a 320x240 resolution.
The 320x200 resolution is very playable even with a modest Pentium, but the 640x480 mode requires something like a Pentium MMX to be playable. Otherwise its a bit of a slideshow.
I would say that the 640x480 software mode looks better than the PS1, but the 3D acceleration mode, at least with the 3dfx Voodoo, looks best of all.
PS1 has higher quality movies. Glidos can play these back with the PC version, but its not free.
Sound :
PS1 beats the PC hands down. There is more CD music in the PS version, whereas the PC game just plays the same background track over and over for each level. The sound effects in the PS1 sound more crisp and clear, presumably because the PC version had to support 8-bit sound cards while the PS1 could handle 16-bit samples.
Using the Tomb Raider Audio Pack will restore the music.
Control :
The PS1 game does not support the Analog controls of the Dual Shock. It is better overall than using a PC keyboard. However, you cannot completely remap the buttons. With all available control schemes, the jump button is ■ and the action button is x. Just as a reminder, here is the PS button layout :
. ▲ .
■ . o
. x .
In virtually all good games up to that point, the position of the buttons the game selects for the action and jump buttons is reversed.
PC version officially supports only 4 buttons using a joystick. If you run it in real mode DOS, this is all you can hope for. As there are more functions than 4 buttons can handle, you may need to use the keyboard. And there are always usual issues that gameport joysticks bring.
Running PC Tomb Raider in Windows or DOSBox allows you to use Joy2Key software to remap your gamepad's buttons to keyboard keys. This allows you to freely configure your gamepad as you like.
