[GNC] XML vs SQL data integrity question

[Jeff]

This has probably been discussed here before but; I'm going ask anyway.  
Which do most people find more reliable with GNC, SQL or the default 
XML?  And are there any features I would lose other than the rollback 
ability with SQL?

I'm getting tired of having to track down account and report issues 
every time Windoze 10 hiccups.  I use the default XML, uncompressed.  
One set of books has been corrupted several times, I'm assuming when 
Windoze just simply kills the GNC program out of the blue.  I have 
another set of books for a business that so far, knock on wood,  the 
only problem is sometimes various buttons have to be selected multiple 
times to work then all of the windows open in GNC blur while processing 
then go back to normal display.

My computers are all networked and dual boot Windoze and Ubuntu, so I 
would need SQL on both sides if I switch over.  I'm leaning towards 
PostgreSQL (pro's, con's?  Suggestions?).
