Let's see if I can help you a bit:

There was, a long time ago, the one original AT&T UNIX. However, it's long been discontinued, with rights going through various hands (see the current Novell vs. SCO squabble). Sometime around the late 1970s, two different systems started to emerge: System V, and the Berkley Standard Distribution. Current Unices are based on those two. For a complete overview, Wikipedia has a pretty good article.
If by "high-end" you mean "expensive closed-source company produced", you won't be able to buy these alone. Those usually come bundled with hardware, and aren't available without it (AIX, HP-UX, and MacOS X are examples of that).
Deciding on what UNIX to use depends on what you want to do. If you want to develop in a wide range of languages, or using the most current hardware, I'd suggest Linux. If you want a stable system (both in terms of run-time and system behaviour), I'd suggest *BSD or OpenSolaris
The hardware modern Intel-based Macs use is pretty much completely PC hardware, so it won't make any difference on stability. But I suggest setting up the new system on different hardware, since it won't be as much trouble should you need to re-install.

Does the assembler output differ between operating systems ?

The assembly code generated by assembler, from a C-source code depends on the CPU architecture underlying it, eg x-86 . Then does the assembler output of a simple C-source code (containing common function-calls of both windows and linux) differ between Operating Systems ?

Perl::OSType(3pm)					 Perl Programmers Reference Guide					 Perl::OSType(3pm)

NAME

       Perl::OSType - Map Perl operating system names to generic types

VERSION

       version 1.003

SYNOPSIS

	 use Perl::OSType ':all';

	 $current_type = os_type();
	 $other_type = os_type('dragonfly'); # gives 'Unix'

DESCRIPTION

       Modules that provide OS-specific behaviors often need to know if the current operating system matches a more generic type of operating
       systems. For example, 'linux' is a type of 'Unix' operating system and so is 'freebsd'.

       This module provides a mapping between an operating system name as given by $^O and a more generic type.  The initial version is based on
       the OS type mappings provided in Module::Build and ExtUtils::CBuilder.  (Thus, Microsoft operating systems are given the type 'Windows'
       rather than 'Win32'.)

USAGE

       No functions are exported by default. The export tag ":all" will export all functions listed below.

   os_type()
	 $os_type = os_type();
	 $os_type = os_type('MSWin32');

       Returns a single, generic OS type for a given operating system name.  With no arguments, returns the OS type for the current value of $^O.
       If the operating system is not recognized, the function will return the empty string.

   is_os_type()
	 $is_windows = is_os_type('Windows');
	 $is_unix    = is_os_type('Unix', 'dragonfly');

       Given an OS type and OS name, returns true or false if the OS name is of the given type.  As with "os_type", it will use the current
       operating system as a default if no OS name is provided.
