IMO, zwłaszcza jeśli porównywano matematycznie wyniki z tych metod.

Simple as that.

This is especially appropriate when there is a numerical comparison. For qualitative, consistency is fine. My choice is backed by several hundred million google hits with the appropriste words.

Examples
1) Bland-Altman analysis was used to assess the agreement between the two methods: BAI and BIA.
2) agreement between the 2 methods, calculated using the kappa estimate, was poorer with spirometry values from women
and from patients at the extremes of height and age.
3) Here there is poor agreement between the two methods of assessing density (95% limits of agreement - 16.90 - 32.46).
4) To assess the agreementbetween bedside glucose (bGlu) measurements and laboratory plasma glucose (pGlu) measurements in the ICU setting
5) Bland-Altman’s analysis and plot are the most common methods used to assess the relative agreement between two analytical methods that measure the continuous variables measured on the same scale.
6) At retail outlets, between-method differences for both anti-malarials and RDTs increased with larger volumes being measured, so mean differences were not a meaningful measure of agreement between the methods.
7) agreement between the two methods in the amount of HE on color and red free photographs and severity of leakage were 85% (K=0.69), 79% (K=0.59) and 72% (K=0.46) respectively.

8) There was a high rate of agreement between the two methods used (97 to 100%).

9)The limits of agreement between the two methods were (−10.83 cm3, 8.39 cm3), ICC was 0.991 (F = 209.61, P < 0.05), and 95% confidence interval is (0.976, 0.996). The results revealed a good agreement between the two examination methods of contrast-enhanced sonography and enhanced MRI.http://informahealthcare.com/doi/abs/10.3109/02656736.2013.8...
10) agreement between the two methods of temperature determination was assessed by calculating limits of agreement within which 95% (±2 standard deviations) of individual differences would fall.
