Pixel-Perfect Dynamic Text works with both orthogonal and perspective cameras. Text can also be aligned and anchored just like with Text Mesh. Also baseline anchor is supported (used by default). Uses the standard built-in font material and shader (which is fast, unlike TextMesh Pro shader). Text can also be set to auto-orient itself towards the camera (like a billboard).

Doesn’t contain native code. Works with both Unity and Unity Pro versions. Supports Desktop, Mobile and Web platforms. Can also be mixed in with the new Unity 2D. Text can be updated as string or with a StringBuilder, so that extra strings won’t be leaked unnecessarily.
