The 318 was one of the first if not the first "video" operational amplifiers. Input degeneration gives high bandwidth and slew rate but also higher noise and less precision. There are modern "video" operational amplifiers which use the same idea but also other types of video operational amplifiers.
318 Faster
324 Slower
318 Dual Supply Part
324 Single Supply Part
318 +/-15 Volt Maximum Differential Input Voltage (1)
324 +/-36 Volt Maximum Differential Input Voltage
The modern AD818 is very similar and I suspect intended as an improved replacement although it does not support external compensation and has a different offset null configuration. Th AD825 is an alternative I would consider because its higher maximum differential input voltage makes it more general purpose.
(1) This matters when used as a comparator.
The LM324 has roughly 10x the bandwidth of the LM318.
You are thinking of the LM308 but even it is not that slow. An LM308 will actually be faster than an LM324 in most applications when properly frequency compensated.
