Both of them are equally good. Both of them having small limitations. Total output is sometimes not obtained from SPSS like AOR in ordinal logistic regression in SPSS, AOR in conditional logistic regression in matched pair case control study in SPSS etc. SPSS will give regression coefficient, but manually u have to calculate e to the power coefficient to obtain AOR. SPSS is more user friendly.
For some advanced statistical methods/tests are available only in SAS, i.e. Panel data analysis; and also SAS is much stronger in programming new methods, i.e. modern time series analysis.
I started using SPSS more than 20 years back. It was fast and easy to use. SAP has additional features which some might more useful. I agree with most that SPSS is more user friendly.
Give a try to JASP (jasp-stats.org) or JAMOVI (jamovi.org), open source and free to use...you would be amazed, and would stop both of the questioned softwares.
