Basically both options are equal. There are some pro and cons for each:
FSUIPC:
+ Offers some Data-Offsets not available in SimConnect
+ extensible via lua
- Update of Values only every 200ms (that's too slow for gauges)
- No FIP-Gauges support FSUIPC
- WideFs costs extra (to seperate Sim and Devices)
- sometimes hard to find the right offset
SimConnect:
+ Datavalues updated as soon and as often as they change (every simulation frame)
+ Change of Dataunits possible ( Cesius instead of Fahrenheit, meters instead of feet)
+ All FIP-Gauges support SimConnect
+ Straight forward naming of the values
+ Required for full support of A2A and PMDG aircraft
+ Support for Majestics Q400 Dash-8 (pro & trainer)
+ No additional costs for splitting Sim and Devices to different computers to save CPU
- not extensible. Datavalues that are not defined by the sim cannot be accessed
If you wanna fly PMDG you must use SimConnect. The PMDG FSUIPC-Dataoffset are currently not supported by SPAD.neXt.
I personally recommend SimConnect, unless you are very familiar with FSUIPC.
But, Of course you can use both simultaneously …
