The original
PCSX-Redux
A PlayStation 1 emulator forked from PCSX, built with debugging and reverse engineering tools.
Replacements
Listings that take over the same core job as PCSX-Redux.
DuckStation
A fast, accuracy-focused PlayStation 1 emulator. Excellent software, but licensed non-commercial and no-derivatives.
DuckStation targets accurate play with hardware renderers and upscaling rather than development tools, and its CC BY-NC-ND licence means it is not open source.
Mednafen
Command-line multi-system emulator covering Saturn, PlayStation and more.
Mednafen covers PlayStation alongside Saturn and other systems, but it is driven from the command line with a text configuration file instead of a debugging interface.
PCSX-ReARMed
A PlayStation emulator forked from PCSX-Reloaded and optimized for ARM devices and handhelds.
PCSX-ReARMed is another PCSX fork, optimized for ARM handhelds and low-power devices, and is mostly distributed as source or through frontends rather than as a desktop app.
BizHawk
A multi-system emulator built for tool-assisted speedrunning, with rewinding, frame stepping, memory search and input recording.
BizHawk adds memory search, frame stepping and input recording across many systems, though it runs only on Windows and Linux and its cores are less accurate.
RetroArch
One front end for dozens of emulators, with unified settings, shaders and a controller setup you only do once.
RetroArch runs PlayStation through downloadable cores in a unified front end with shaders and controller setup, but it lacks PCSX-Redux's PS1 development tools.
Similar software
Related functionality, not a direct replacement.
PCSX2

Mesen
Cycle-accurate multi-system emulator with a serious debugger.
no$gba
A Game Boy Advance, Nintendo DS and DSi emulator with a source-level debugger.
PPSSPP
A PSP emulator that needs no BIOS file and runs handheld games in HD on phones and PCs.
