I'm currently upgrading my VLB system. It is based on the Aquarius MB-4DUV motherboard, currently runs a Cyrix 5x86-100, has 32MB 60ns RAM and a Paradise 4030 cache controller.
Few days ago I got a nice Cirrus Logic GD5428 VLB in the mailbox, it had 1MB and I upgraded to 2MB. This works fine and provides some bonus colours and resolution over the old GD5424.
This afternoon I managed to repair an Advance Logic ALG2228 VLB 1MB which had broken traces (actually fixed a bad earlier repair attempt by three previous owner). After testing it seems to be a little faster (~5-10%) than the 5428 in DOS benchmarks. The downside is, there are no sockets for ram upgrade, so no 16b colours at 1024 resolution. I can live with that.
Now I know the Cirrus had pretty good compatibility with everything, but for the ALG it's just guessing to me.
They both are not the fastest cards in VLB kingdom but they are all I have. Actually I don't need to have the fastest cards in the world.
I've got a K6-3+ with voodoo3, also good and fast DOS support.
I've got a 386 DX 40 with ISA GD542x too.
So instead on pure speed I think I need best general support.
So how would the ALG do, compared to the GD5428?
